feat(agent): stamp an absolute emittedAt on persisted run events (#3519)

elapsedMs is measured from the encoder's construction, so reading it correctly requires knowing which encoder instance produced it — the anchor ambiguity behind three of the four attempts it took to land elapsedMs at all (#3483 clocked run-chunk-mirror, #3497 clocked hosted-lifecycle; both were correct fixes to encoders production does not use).

emittedAt has no anchor. Stored as epoch milliseconds: comparable without parsing, and roughly a third of the bytes of an ISO string on a stream carrying thousands of events per run.

Both fields are kept because they fail differently — a wall clock can step backwards under NTP correction and yield a negative duration; performance.now() cannot. emittedAt is the durable record, elapsedMs the trustworthy intra-run measure.

Unlocks created_at − emittedAt as ingest lag: the gap that produced the phantom "metronomic 30ms delta cadence" in the original trace analysis becomes measurable rather than a trap.

Also included: a refactor forwarding encoder timing as one timing options object instead of re-declaring each clock through four wrapper layers. Net-negative diff, no behaviour change — and it means adding a future clock is one edit rather than a sweep, which is structurally the same failure this field already went through.

Version files

deno.json, src/utils/version-constant.ts, and src/html/hydration-script-builder/hydration-runtime.generated.ts — all three at 0.1.1224.

Cut with --no-test --no-build; --no-build remains mandatory until issue #435 (deno task verify:dist does not exist) is fixed.
