Recover from client chunk load failures

[cursor]

Changes

• Added production-only client recovery for chunk load failures that reloads the current page once per failed chunk cooldown.
• Tagged chunk load Sentry events with chunk_load_recovery: attempted.
• Suppressed the known React $RS parentNode follow-up error when it occurs immediately after a chunk load failure.
• Added unit coverage for chunk load detection, reload cooldown behavior, and the React follow-up error matcher.

Testing Criteria

• yarn test "src/utils/chunkLoadRecovery.test.ts" --runInBand
• yarn lint:check (passes with existing warnings)
• yarn tsc --noEmit currently fails on pre-existing missing SVG module declarations in src/icons/index.ts.

Notes

• Root Sentry event: TASKS-8E / Linear OUT-3776.
• No dependency or config changes required.

Impact & Surface Area of Change

• Client Sentry instrumentation and production browser error handling for chunk load failures.
• Expected behavior: a transient or stale chunk failure triggers a single reload attempt, preserving the URL, instead of leaving the user on a broken React stream resume state.
