naorpeled 982a91d5e8 fix: resolve open GitHub security findings
Code scanning (js/polynomial-redos, alerts #16 and #17)
-------------------------------------------------------
bowser applies these regexps to attacker-controlled User-Agent strings, and
four of them ran in quadratic time:

  * The "Something else" fallback used /^(.*)\/(.*) / and
    /^(.*)\/(.*)[ \t]\((.*)/. Two unbounded `.*` before a required literal
    make the split ambiguous, so a UA of "/a" repeated backtracks O(n^2).
    Greedy `(.*)` always picks the last `/` that still has the delimiter
    after it, so the second group can never span a `/` -- narrowing it to
    `[^/]*` is exactly equivalent and removes the ambiguity. Verified
    identical on 1,000,000 fuzzed inputs and on the full acceptance corpus.

  * The Linespider and SlackBot version regexps used `(?:-[-\w]+)?` before a
    required `[\s/]`. Since `[-\w]` and `[\s/]` are disjoint the backtracking
    is pure waste, but the engine still walks it once per start position, so
    "linespider-" repeated is quadratic. Bounding the run to `{1,64}` makes
    it linear; no real bot-name suffix approaches 64 characters.

A sweep of all 253 regexp literals in src/ (fuzzed for superlinear scaling,
with the four pre-fix patterns used to confirm the detector works) reports no
remaining superlinear regexps. test/unit/redos.js locks this in.

Actions (actions/missing-workflow-permissions, alerts #5 and #15)
-----------------------------------------------------------------
merge-to-master.yml and draft-or-update-next-release.yml had no `permissions`
block and so inherited the default token. Both now declare least privilege,
matching publish.yml and pull-request.yml.

Dependabot (22 open alerts, all development scope)
--------------------------------------------------
bowser ships no runtime dependencies, so none of these reached consumers, but
they were live in CI. `pnpm audit` goes from 29 advisories to 0:

  * jsdoc 3 -> 4 (with docdash 1 -> 2) drops taffydb, which has no patched
    release, and picks up current markdown-it/linkify-it.
  * coveralls -> coveralls-next 6 drops `request`, which is deprecated with no
    patched release, along with form-data, qs 6.5.x, uuid 3 and tough-cookie 2.
    Same `coveralls` bin and same stdin contract; lcov conversion verified.
  * gh-pages 3 -> 6 clears the critical prototype pollution advisory.
  * pnpm overrides pin the remaining transitive-only advisories to the lowest
    patched release on each existing major.

Verified: pnpm audit clean, lint clean, 346 tests pass (the acceptance corpus
runs against both src/ and the built es5.js), build, package smoke test, and
doc generation.

/**
* Browsers' descriptors
*
* The idea of descriptors is simple. You should know about them two simple things:
* 1. Every descriptor has a method or property called `test` and a `describe` method.
* 2. Order of descriptors is important.
*
* More details:
* 1. Method or property `test` serves as a way to detect whether the UA string
* matches some certain browser or not. The `describe` method helps to make a result
* object with params that show some browser-specific things: name, version, etc.
* 2. Order of descriptors is important because a Parser goes through them one by one
* in course. For example, if you insert Chrome's descriptor as the first one,
* more then a half of browsers will be described as Chrome, because they will pass
* the Chrome descriptor's test.
*
* Descriptor's `test` could be a property with an array of RegExps, where every RegExp
* will be applied to a UA string to test it whether it matches or not.
* If a descriptor has two or more regexps in the `test` array it tests them one by one
* with a logical sum operation. Parser stops if it has found any RegExp that matches the UA.
*
* Or `test` could be a method. In that case it gets a Parser instance and should
* return true/false to get the Parser know if this browser descriptor matches the UA or not.
