fix(hygiene): [#1052 D8 review-fix follow-up] scrub example strings from scanner source

The consensus review-fix for D8 (commit 0ffc42db97) added concrete tracker-
key literals to the scanner's own test file and doc comments — e.g. inside
`test.each([...])` fixtures, in the block comment above `RULES`, and in the
pre-push hook comment. Those are the exact strings the scanner is meant to
catch, so a pre-push run flagged them on this branch. That defeats the
purpose: no example strings should appear as grep-visible literals in a repo
whose whole rule is "don't put those literals here."

Fix:
- Test fixtures now build the strings at runtime from split prefix + digits
  (`const PREFIX = "A" + "I"`, `key(1234, "foo")` etc). The regex still sees
  what it needs to test; a source grep for the pattern finds nothing.
- Scanner source comment loses its verbatim example strings — the intent is
  clear from the code + tests.
- `.husky/pre-push` comment stops naming a specific pattern host; the
  scanner's own RULES are the source of truth.
- Path-allowlist added in the same commit is no longer needed and dropped —
  keeps the guard strict for everyone.

Verified: `bun test packages/opencode/test/skill/tracker-leak-check.test.ts`
still 28/28 pass; scanner reports clean on the working tree.

-// #1052 D8 review-fix (M6): self-test for the tracker-leak scanner's regexes.
-// The scanner is the sole guard against internal-tracker refs landing on the
-// public repo. If its regex regresses, the whole hook is silently useless. The
-// original `\bAI-\d+\b` had exactly that bug — it missed `AI-1234foo` /
-// `AI-1234_bar` because a trailing word char defeats the ending word-boundary.
-// Consensus review flagged this as CRITICAL. These tests pin the regex
-// against the specific suffix classes it must catch, plus the negative cases
+// Self-test for the tracker-leak scanner's regexes. See
+// `script/check-tracker-leaks.ts`. The scanner is the sole guard against
+// internal-tracker references landing on this public repo — if its regex
+// regresses, the guard silently stops working. These tests pin the regex
+// against representative suffix classes it must catch plus the negatives
 // that must remain clean.
 //
-// If you edit `script/check-tracker-leaks.ts` RULES and this test still passes,
-// you probably didn't regress the guard. If a case here starts failing, either
-// the regex changed intentionally (update the test) or the regex broke silently
-// (the whole point of this file).
+// Fixture note: this file is on a public repo that forbids concrete
+// project-prefixed tracker keys in source. Test inputs are therefore built
+// at runtime from a helper — `key(1234, "foo")` produces the exact string
+// the regex needs to see, but the literal never appears in git-searchable
+// source. Grep the repo for `\bAI-\d+` and this file returns nothing.
