fix(governance): rename CLAUDE.md TypeScript exemptions heading to match workflow regex (#374)

## Summary

The `governance / Language / package anti-pattern policy` job in the
reusable
[governance-reusable.yml](https://github.com/hyperpolymath/standards/blob/main/.github/workflows/governance-reusable.yml)
scans `.claude/CLAUDE.md` for a section heading matching the regex
`TypeScript [Ee]xemptions` to find the exemption table.

This repo's heading was `### TypeScript / JavaScript Exemptions
(Approved)`. The `/ JavaScript ` between the two words prevents the
regex from matching.

The parser then falls through to the next mention of the phrase ("the
TypeScript exemptions above") in the **Runtime Exemptions** section's
prose, and parses the **Runtime Exemptions** table — picking up 2 JS
entries (`packages/affinescript-cli/mod.js`,
`editors/vscode/test/**/*.js`) instead of the 3 TypeScript entries
(including `affinescript-deno-test/*.ts`).

Result:
`affinescript-deno-test/{cli,example/smoke_driver,lib/{compile,discover,runner}}.ts`
were reported as forbidden TypeScript files on every PR — blocking the
check estate-wide for weeks.

## Fix

Rename `### TypeScript / JavaScript Exemptions (Approved)` → `###
TypeScript Exemptions (Approved)`.

JavaScript exemptions already live in their own `### Runtime Exemptions
(Approved)` section immediately below, so the original heading's `/
JavaScript` was misleading anyway.

## Verification

Simulated the workflow's Python parser locally on the post-fix
`.claude/CLAUDE.md`:

```
Parsed 3 exemption(s)
✅ No TypeScript files outside allowlist (3 per-repo exemption(s) parsed).
```

(Pre-fix: parsed 2 exemptions — the wrong table — and 5
`affinescript-deno-test/*.ts` files were reported bad.)

## Test plan

- [x] Local Python simulation of the workflow parser
- [ ] CI: `governance / Language / package anti-pattern policy` green on
this PR
- [ ] Downstream: re-run CI on #370, #371, #372, #373 — same check
should turn green after merge

 The "no new TypeScript" / "no new JavaScript" rules have approved exemptions in this repo. These paths are *not* policy violations — they are documented carve-outs because the file format or downstream consumer requires the source language. They are honoured by Hypatia's scanner via path-based exemption + the per-repo CLAUDE.md exemption tables.
