1.1.0-alpha2: bundle 1.0.1 correctness fixes Cherry-picks the four 1.0.1 fixes onto the 1.1.x branch so operators upgrading 1.0.0 → 1.1.0 directly get all the corrections without going through 1.0.1. - request_id strict-regex validation in BeaconRequest. - Top-level try/catch in BeaconController::receive() preserving the docblock 'never 5xx' contract. - Cwv-rid Server-Timing entry skipped on shared-cacheable responses (prevents request-ID corruption on edge-cached pages). - PERFORMANCE.md sampling-rate clarification (the multiplied effective rate). No new 1.1.0 features beyond what alpha1 shipped (outlier filtering, per-metric/adaptive sampling, deploy-event annotations); alpha2 is purely the merged correctness fixes. See ROADMAP.md 1.0.1 and 1.1.0 entries for full descriptions.
