chore(#3465): remove 22 verified-vestigial allow-test-rule markers (#3494)

Phase 1 of #3464. Removes the `// allow-test-rule:` marker from 22 test files
where it is provably vestigial, and tightens the ratchet ceiling in
scripts/lint-allow-test-rule-refs.ceiling.json from 305 to 285.

Eligibility is decided by two independent AST discriminators, both
conservative (any doubt => keep):

(a) Read-target type. Every readFileSync/readFile call in the file resolves
    statically to a prose/config extension (.md/.json/.yml/.yaml/.toml/.txt),
    or the file performs no reads at all. Any read of a source extension
    (.cjs/.js/.mjs/.ts/.cts/.mts/.jsx/.tsx), any dynamic/unresolvable path,
    and any other extension all disqualify the file.

(b) Marker context. Every `allow-test-rule:` occurrence is a genuine comment
    node, never string- or template-literal payload. A marker that lives
    inside a RuleTester `code:` fixture is test DATA, not a suppression
    directive; stripping it corrupts the test. tests/eslint-rules.test.cjs is
    the one such fixture host and is deliberately untouched.

An earlier attempt at this phase classified markers by "strip it and see if
local/no-source-grep still passes" and was reverted in full before commit.
That oracle is unsound: the rule only fires on a literal .cjs/.js/.ts path
containing a quoted bin/lib/gsd-core/src segment, tracked one hop from the
binding, so files that genuinely source-grep real JavaScript pass it
silently -- tests/no-unbounded-spawn-allowlist.test.cjs (reads test sources
through a listTestFiles() walk) and tests/claude-imperative-reference.test.cjs
(matches bin/install.js through an intermediate variable) both cleared it
while being real source-greps. The rule's implementation is narrower than its
intent, so it cannot adjudicate whether an exemption is load-bearing.

Scope is limited to comment deletions: the diff over the test tree is 100%
line removals with zero insertions, and no executable line is altered.

On the ceiling value. The measured count at this HEAD is 283, so 285 leaves 2
slack -- deliberate, and well inside the documented grace band of 3. Pinning
the ceiling to the exact count makes this change effectively unmergeable: any
concurrent PR that lands one marker-bearing test file re-reds it. That race
fired twice while preparing this branch (once mid-rebase taking the count
304->305 on next, once between rebase and the verification run taking it
282->283), and it is the same race that broke next in #3461. A ceiling of
actual+2 preserves a merge window while still ratcheting 305 -> 285.

Known limit, disclosed rather than papered over: this clears 22 of 303
markers and does not reach #3464's trend-to-zero goal. Most of the remaining
markers sit on dynamic-path reads, commonly a hoisted `const p =
path.join(tmpDir, 'STATE.md')` whose target is prose but is unresolvable to
this classifier. A stricter one-hop const resolution would flip an estimated
95 more; that is deliberately left to a follow-up so it can be reviewed on
its own evidence.

Marker discovery reads bytes rather than shelling out to grep:
tests/security-prompt-injection.security.test.cjs carries a literal NUL byte
(an intentional injection fixture) that makes grep treat it as binary and skip
it, which is why the true marked-file count is 303 and not the 302 a shell
scan reports.

Closes #3465
