Adds the afterRead hook factory for per-collection opt-in automatic VIEW
audit entry emission. Fire-and-forget design ensures failing sinks never
propagate to the user-facing read. Includes sentinel IP/UA fallbacks,
truncateIp /24 integration, shouldSkip predicate, and system actor
resolution. All 6 TDD test cases pass; both barrels updated.

Adds createAuditErasureHook in core-audit/src/hooks/. The factory returns
a CollectionAfterDeleteHook that calls auditLog.eraseSubject() when a
document is deleted. Defaults to "pseudonymize" mode; coerces numeric ids
to string; skips undefined/null/object ids. Barrel at hooks/index.ts.
6 unit tests cover all guard branches.
