Tom Boucher 918f987a19 feat(#2982): extend no-source-grep lint to catch var-binding readFileSync.includes() (#2985)
* feat(#2982): extend no-source-grep lint to catch var-binding readFileSync.includes()

The base lint (scripts/lint-no-source-grep.cjs) only catches
readFileSync(...).<text-method>() chained directly. The much more
common var-binding form escapes it:

  const src = fs.readFileSync(p, 'utf8');
  // 50 lines later
  if (src.includes('foo')) {}        // ← still grep, lint missed it

Scan of the test suite found ~141 files using this pattern.

Implementation built TDD per #2982 with structured-IR assertions:

  scripts/lint-no-source-grep-extras.cjs
    - detectVarBindingViolations(src) — pure detector, two passes:
      pass 1 collects vars bound from readFileSync, pass 2 finds any
      <var>.<includes|startsWith|endsWith|match|search>( on those vars.
    - detectWrappedAssertOkMatch(src) — flags
      assert.ok(<expr>.match(...)) which escapes the assert.match rule.
    - VIOLATION enum exposes stable codes for tests to assert on.

  scripts/lint-no-source-grep.cjs
    - Wires the new detectors into the existing per-file check; one
      additional violation row per file with the first 3 sample tokens.

  tests/bug-2982-lint-var-binding.test.cjs
    - 13 tests, all assertions on typed VIOLATION enum / structured
      records. Covers all 5 text-match methods, multi-var, no-bind,
      string literal (must NOT trigger), wrapped assert.ok(.match),
      and assert.match (must NOT double-flag).

Migration backlog (#2974 expanded scope):

  - 42 files annotated `// allow-test-rule: source-text-is-the-product`
    (legitimate — they read .md/.json/.yml files whose deployed text
    IS the product)
  - 3 files annotated `// allow-test-rule: pending-migration-to-typed-ir [#2974]`
    (read .cjs/.js source — clear migration debt)
  - 95 files annotated `pending-migration-to-typed-ir [#2974]` with
    `Per-file review may reclassify as source-text-is-the-product
    during migration` (mixed — manual review under #2974)

After this lands the lint reports 0 violations on main; new
violations in PRs surface immediately.

Closes #2982
Refs #2974

* test(#2982): fix truncated test name per CR

The label ended with a bare '(' from a copy-paste mishap. Now reads
'does NOT flag .matchAll(...) — matchAll is not match, so
assert.ok(.matchAll(...)) is not flagged'.

* chore(#2982): add changeset fragment for PR #2985

Changeset Fragments

This directory holds per-PR CHANGELOG fragments. Every PR with user-facing changes drops one (or more) <random-name>.md files here describing its CHANGELOG entry. Fragments are consolidated into the top-level CHANGELOG.md at release time.

Why

Two PRs that both edit the ### Fixed block of CHANGELOG.md always conflict on merge — git can't pick a serialization order without human input. Two PRs that each add a fresh .changeset/<unique-name>.md never conflict because they don't share lines.

See #2975 for the full rationale.

Adding a fragment

node scripts/changeset/new.cjs \
  --type Fixed \
  --pr 1234 \
  --body "fix the thing — explain the user-visible change in one sentence"

This writes .changeset/<adjective>-<noun>-<noun>.md with frontmatter and a body. Three random words → concurrent PRs don't collide.

Format

---
type: Fixed
pr: 1234
---
**`/gsd-foo` no longer drops trailing slashes** — explain the user-visible change.

Allowed type: values follow Keep a Changelog: Added, Changed, Deprecated, Removed, Fixed, Security.

Opting out

PRs that legitimately have no user-facing impact can add the no-changelog label. CI honors it. When unsure, add the fragment.

At release time

node scripts/changeset/cli.cjs render --version vX.Y.Z --date YYYY-MM-DD

Reads every fragment, groups bullets by type:, replaces ## [Unreleased] with a new ## [vX.Y.Z] - YYYY-MM-DD block, opens a fresh ## [Unreleased] above, deletes consumed fragments. Idempotent.
