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

The governance-reusable.yml workflow scans .claude/CLAUDE.md for a section
heading matching the regex `TypeScript [Ee]xemptions` to find the exemption
table. The heading was `### TypeScript / JavaScript Exemptions (Approved)`,
which does not match because "/ JavaScript " sits between the two words.

Consequence: the parser fell through to the next mention of the phrase
("the TypeScript exemptions above") in the Runtime Exemptions section's
prose, then parsed the Runtime Exemptions table (2 entries: `mod.js`,
`editors/vscode/test/**/*.js`) instead of the TypeScript Exemptions
table (3 entries including `affinescript-deno-test/*.ts`).

Result: `affinescript-deno-test/{cli,example/smoke_driver,lib/{compile,discover,runner}}.ts`
were reported as bad on every PR, blocking the `governance / Language /
package anti-pattern policy` check estate-wide.

Rename to `### TypeScript Exemptions (Approved)`. JS exemptions already
live in their own `### Runtime Exemptions (Approved)` section just below.

Verified locally: parser now picks up 3 exemptions; 0 bad .ts files reported.

 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.
