Add `src/core/usage-policy/`, the single shared, cwd-agnostic matcher for the
`.hypignore` folder-scoped usage policy. V1 enforces only the capture seam; this
task lands the core module the Claude/Codex adapters (T2/T3) and the CLI (T4)
will import.
- `format.js` `parseHypignore`: strip `#`/blank lines, first token is the class;
empty/comment-only => `ignore`; unknown/unimplemented token => `ignore` + a
`warn` string (the privacy fail-safe). `@ref LLP 0049#file-format`/`#fail-safe`.
- `matcher.js` `createUsagePolicyResolver({readFileSync,existsSync})`:
gitignore-style ancestor walk from a cwd to the nearest `.hypignore`, per-cwd
memo cache, fs injected. `resolve(cwd)` -> `{class,governedBy,declared}`,
`isIgnored(cwd)`. `@ref LLP 0050`/`LLP 0049#scope`.
- `index.js` barrel + `types.d.ts` (`UsageClass`, `ParseResult`, `ResolveResult`,
`UsagePolicyResolver`).
- Tests `test/core/usage-policy.test.js`: empty=>ignore, unknown=>ignore+warn,
nearest-ancestor wins, no file=>full, cache stable + reads once.

Implements task T1 of hypignore-usage-policy: the shared core matcher in
src/core/usage-policy/(format parser, ancestor-walk resolver with per-cwd cache, barrel, types) plus traditional tests. Realizes LLP 0049/0050/0052; capture-seam adapters (T2/T3) and CLI (T4) consume this module.Task-Id: T1
