feat(web): wire feature-flag and kill-switch platform clients

Browse Source 
- Added @bytelyst/feature-flag-client and @bytelyst/kill-switch-client deps
- Created web/src/lib/feature-flags.ts — poll-based flag client (fail-open)
- Created web/src/lib/kill-switch.ts — kill-switch check client (fail-open)
- Telemetry, diagnostics, extraction were already wired

Verification: web typecheck + 6 tests pass.
