225a76c9cb (core) Don't throw error in onRecord(s) for insufficient access for includeColumns
Summary:
This removes checking for full access in `onRecord/onRecords` when `includeColumns` is a non-default value. The check had two problems:

1. It relied on the access level being present in the URL query parameters, which doesn't work if the page has redirected. See the discussion in https://grist.slack.com/archives/C0234CPPXPA/p1702576602615509. There seems to be no way to reliably and synchronously check the access level.
2. Calling `onRecords` before `ready` and forgetting to handle an error from the access check meant that `ready` wouldn't be called, so Grist couldn't request the correct access level from the user. I made this mistake and it seems like a nasty footgun.

Ultimately this has no effect on security, as an error will still be raised, but in a place where the widget developer can't catch it. They'll still see an error message in the console, and they can still check the access level reliably using `onOptions`, so I think this is OK.

Test Plan: Updated nbrowser test

bd52665f96 (core) Allow adding rows to widgets filtered by a link using a formula column
Summary:
When a widget `A` is selected by a widget `B` so that `A` is filtered, adding a new row to `A` uses the values in the selected row of `B` and the columns relevant to the linking as default values for the new row. This ensures that the new row matches the current linking filter and remains visible. However this would previously cause a sandbox error when one of the linking columns was a formula column, which doesn't allow setting values. This diff ignores formula columns when picking default values.

Since the value of the formula column in the new row typically won't match the linking filter, extra measures are needed to avoid the new row immediately disappearing. Regular filters already have a mechanism for this, but I didn't manage to extend it to also work for linking. Thanks @dsagal for creating `UnionRowSource` (originally in D4017) which is now used as the solution for temporarily exempting rows from both kinds of filtering.

While testing, I also came across another bug in linking summary tables that caused incorrect filtering, which I fixed with some changes to `DynamicQuerySet`.

Test Plan: Extended an nbrowser test, which both tests for the main change as well as the secondary bugfix.

a1c62f32f4 (core) Fix selecting new row in chain of filter links
Summary:
When the 'new' row of a table is selected, another table filter linked to the first shows no data. This diff ensures that a third table filtered by the second also shows no data, i.e. that it behaves the same as if the second table was also on the 'new' row. Video of the bug: https://grist.slack.com/archives/C069RUP71/p1692622810900179

The functional code is copied almost verbatim from https://github.com/gristlabs/grist-core/pull/666 by @jvorob which was working correctly. A comment there mentioned a possible bug where:

> ...you can have the grayed-out "No row selected" text from disableEditing but still have rows showing up in the section. Haven't been able to reproduce...

I noticed this behaviour when I copied only part of the fix, but it disappeared after copying the whole thing, so it seems likely to me that this is why it couldn't be reproduced.

Test Plan: Added a new nbrowser test with a new fixture, which also tests filter link chains and selecting the new row more generally, since I couldn't find other tests of this.

4d9bbf6263 (core) Exit more cleanly on unhandled errors, and handle errors writing to Clients.
Summary:
- Node has a strong recommendation to assume bad state and exit promptly on
  unhandled exceptions and rejections. We follow it, and only make an effort to
  clean up before exiting, and to log the error in a more standard way.

- The only case seen in recent month of an unhandled rejection was for
  attempting to write overly large JSON to a Client websocket. Ensure that's
  handled, and add a test case that artificially reproduces this scenario.

Test Plan:
Added a test case for failing write to Client, and a test case that unhandled
errors indeed kill the server but with an attempt at cleanup.

allow bundled widgets to be hidden from dropdown, and nested (#714)
This makes a few refinements to bundling widgets:

  * A widget with `published: false` is not shown in the
    custom widget dropdown in the UI. This is so widgets
    can be bundled with the app for "native" use (like the
    calendar widget) without immediately resulting in an
    extra listing in the UI. (There are improvements we'd
    like to make to the UI to better communicate widget
    provenance and quality eventually, which would be a
    helpful alternative to just a binary flag.)

  * A relative path to the custom widget manifest is
    respected. This will make the bundling process marginally
    neater.

cc9a9ae8c5 (core) support for bundling custom widgets with the Grist app
Summary:
This adds support for bundling custom widgets with the Grist app, as follows:

 * Adds a new `widgets` component to plugins mechanism.
 * When a set of widgets is provided in a plugin, the html/js/css assets for those widgets are served on the existing untrusted user content port.
 * Any bundled `grist-plugin-api.js` will be served with the Grist app's own version of that file. It is important that bundled widgets not refer to https://docs.getgrist.com for the plugin js, since they must be capable of working offline.
 * The logic for configuring that port is updated a bit.
 * I removed the CustomAttachedView class in favor of applying settings of bundled custom widgets more directly, without modification on view.

Any Grist installation via docker will need an extra step now, since there is an extra port that needs exposing for full functionality. I did add a `GRIST_TRUST_PLUGINS` option for anyone who really doesn't want to do this, and would prefer to trust the plugins and have them served on the same port.

Actually making use of bundling will be another step. It'll be important to mesh it with our SaaS's use of APP_STATIC_URL for serving most static assets.

4e67c679b2 (core) Options for plugin API functions which fetch data from the selected table or record
Summary:
Adds a new interface `FetchSelectedOptions` with three keys (including the preexisting `keepEncoded`) and adds/updates an optional `options: FetchSelectedOptions` to six related functions which fetch data from the selected table or record. The `keepEncoded` and `format` options have different default values for different methods for backwards compatibility, but otherwise the different methods now have much more similar behaviour. The new `includeColumns` option allows fetching all columns which was previously only possible using `docApi.fetchTable` (which wasn't always a great alternative) but this requires full access to avoid exposing more data than before and violating user expectations.

Eventually, similar options should be added to `docApi.fetchTable` to make the API even more consistent.

Discussion: https://grist.slack.com/archives/C0234CPPXPA/p1696510548994899

9b36fb4dab (core) Fix error in sandbox when removing multiple summary source columns
Summary:
Fixes a very specific bug reported here: https://grist.slack.com/archives/C069RUP71/p1694630242765769

The error occurred when:

1. Removing multiple columns simultaneously
2. Those columns were sources of groupby columns for a summary table (so removing them meant recreating the summary table and thus deleting its columns)
3. There was a display column for one of the columns that got deleted (either directly or indirectly) which was set to be automatically removed since it was no longer needed, but this failed because the column was already deleted as part of earlier table removal.

I fixed this by making `apply_auto_removes` remove table records last, so removing the display column wouldn't be a problem.

That fixed the original error, but then I noticed that trying to undo the removal could lead to another error (under even more specific circumstances). It's hard to see exactly why, but I can see that just 3 `RemoveColumn` user actions generated over 100 doc actions and corresponding undo actions, hence the difficulty in narrowing the problem down. This is partly because removing a single column would recreate a summary table, only for that table to be immediately replaced again when another column was removed. Making the frontend send a single `[BulkRemoveRecord, _grist_Tables_column, ...] ` leads to a more efficient and sensible process with about half as many doc actions and no undo error. I think this alone would also solve the original error, but the data engine change seems more generally helpful and worth keeping.

Bidirectional Linking (#622)
Allows bidirectional / cyclic linking for same-record cursor links.
This should allow multiple sections to all synchronize their cursors,
such that clicking in any one of them will move all the others.

Works even if some sections in the cycle have rows filtered out (the 
filtered-out sections might desync their cursors, but the correct cursor
position will still propagate downstream, and they'll re-sync if clicking on
a row that is present in them)

Under the hood, each cursor has a _lastEditedAt counter, updated when
a user's action changes the cursor in a section, such that we can always
tell which section was touched most recently. This is used to resolve
conflicts stably when dealing with cycles or chains of cursor-links.

Updated selectBy and recursiveMoveToCursorPos to handle cycles

Updated tests for selectBy behavior

However, main bidirectional-linking tests are not in this commit, they'll come in a subsequent PR
