mathiasandClaude Opus 4.8 f5021a8436 feat(youtube): process-wide caption-fetch rate gate (ADR-014 item 2) 
ADR-014 item 2 — a single per-egress-IP rate gate shared by every caption
fetch — was specced but only per-video backoff (rate_limited_at) shipped.
Build the real gate now: it is load-bearing once ADR-018 puts auto-summarize
on an in-process schedule across multiple users (all fetches leave one pod's
egress IP, concurrently with live "Summarize" clicks — without a shared gate
that self-inflicts 429s every cycle).

globalFetchGate (golang.org/x/time/rate, default 2s/req burst 1) is consulted
in httpDo before every live outbound fetch — player, watch-page, timedtext —
so the scheduler runners and the web click-path serialise through one limiter
regardless of how many users/goroutines are upstream. The test seam
(a.transport != nil) skips the gate so fakes are not throttled.

TAPIR_FETCH_RATE (Go duration, default 2s, 0 = unlimited) wires SetFetchRate in
cmdRun; the existing per-video backoff stays as the complementary 429 handler.

mathiasandClaude Opus 4.8 ce2fc62ef8 feat(config): TAPIR_FETCH_BACKOFF for rate-limit retry window 
Adds FetchBackoff (Go duration, default 1h) controlling how long the run loop
waits before re-fetching a transcript that returned HTTP 429. Zero means always
retry. Not required by ValidateForRun — a zero/unset value is a valid policy.

Worker F's README told users to 'cp .env.example .env' but a blanket .env.*
gitignore rule silently dropped it. Un-ignore .env.example (real .env stays
ignored) and generate the template from internal/config: every TAPIR_* var,
which command needs it, accurate defaults, op/port-forward notes for demo time.
