Symmetric to the @hypaware/claude T2 drop: enforce the `.hypignore` folder-scoped `ignore` usage policy at the Codex capture seam, the only place that resolves a `cwd`, so an ignored exchange never reaches the cache. - `codex/src/exchange-projector.js`: `createCodexExchangeProjector` holds one shared `createUsagePolicyResolver()` (per listener; injectable for tests). Once the exchange `cwd` is resolved, an ancestor `.hypignore` of class `ignore` returns no projection, so the gateway source's `messageRows.length > 0` write guard persists nothing. The response has already streamed, so the live LLM call is untouched (LLP 0049 R1/R2). Emits a structured `usage_policy_drop` log (hashed cwd, governing path). - `codex/src/backfill.js`: `createCodexBackfillProvider` holds one resolver and skips a session whose recorded `cwd` is ignored before projecting/yielding, so `hyp backfill` never re-imports sessions ignored live (LLP 0049 R1). Adds `sessions_ignored` to the scan-complete telemetry. The projector returns `undefined` (its established skip signal — the dispatcher maps it to an empty rows array, the "return []" of LLP 0050 §Live); returning a literal `[]` would trip the gateway's invalid-projection warning. No cache schema, export driver, gateway, or settlement change — capture-seam only, per LLP 0050. Tests mirror T2: ignored cwd -> no rows/skip, clean cwd unaffected, drop telemetry emitted; the real shared matcher is exercised via injected fs. @ref LLP 0050 [implements] Task-Id: T3 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Implements task T3 of hypignore-usage-policy: the Codex adapter capture-seam drop, symmetric to T2 (claude).
