Via e6cdf4abb1 feat(engine): opt-in per-frame timing on fast-capture fallback path ...

Field-signal baseline: >=2 fallbacks/hr on darwin/arm64 from filter:blur
and filter:drop-shadow triggers. Fallback path perf is currently untimed,
so we can't know if the overhead is 10% or 10x. This PR adds opt-in
per-frame timing (HF_PROFILE_FALLBACK_CAPTURE=true) that emits p50/p95/p99
+ trigger reason via the observeRenderStage telemetry channel extended in
#2510. Diagnostic surface only -- no perf fix, no behavior change on
healthy paths.

Stack: PR #9 (final) of 9 (base via/escape-hatch-fallback-reproducer).
