Extends the fake-nip-07-extension harness to a multi-session flow that publishes
a watch history via the app (real chunking + encryption through the fake
extension), then reloads to measure the decrypt-cache effect by counting
nip44.decrypt extension round-trips:
seed : publishes the snapshot (nip44.encrypt per chunk)
COLD : first reload — decrypts chunks via the extension (~180 calls @ 300 items)
WARM : second reload — decrypt cache hits, ~2 calls
Validates the watch-history decrypt cache (watchHistoryDecryptCache.js): the
warm reload skips ~180 serialized extension round-trips (~9s @ 50ms, more at
real latency). Uses context-level bindings so localStorage (and the cache)
persists across reloads; bypasses feed signature verification of seeded data via
the test-only videoEventVerifier hook so the feed renders deterministically.
Also surfaced: cold load still pays the full decrypt cost, and the decrypt path
makes far more extension calls than there are chunks — an inefficiency to chase.

The UX harness (fake nip-07 extension) revealed that the off-thread verification
could blank the feed: if nostr-tools is slow/unable to load inside the verify
worker, the worker hangs, each batch waits the full 10s timeout, and the
main-thread fallback could return an empty set (fail-closed) — dropping every
event so no videos ever render, silently (devLogger is suppressed in prod).
Harden it so verification can never stall or blank the read feed:
- Worker timeout 10s -> 2.5s, and disable the worker for the session after one
timeout/error so we never pay the timeout on every batch.
- Bound the main-thread nostr-tools wait (Promise.race ~2s) so a slow/failed
load can't hang the fallback.
- Fail OPEN when the verifier is genuinely unavailable: pass events through
unverified rather than dropping them (the pool already does not verify, so this
does not regress the prior posture). Real verification still runs whenever
nostr-tools is available.
Adds a regression test (hung worker -> resolves via fallback, worker disabled).
Also updates the harness to seed mode:"live" videos + a NIP-65 relay list for
mock-relay isolation.

Lets the agent observe the real app the way a user does: runs bitvid in headless
Chromium against an in-process mock relay, injects a fake window.nostr extension
backed by Node-side nostr-tools crypto (via page.exposeFunction) with a
serialized ~100ms latency queue to model a real extension. Drives the real
nip-07 login flow, isolates to the mock relay via a seeded NIP-65 list, and
captures console logs, per-method extension call counts, feed-render timing, and
screenshots.
Phase 1 (this commit) verifies fake-extension login + relay isolation + metrics.
Already surfaced a stuck "Fetching recent videos…" state to investigate. Next
phases: seed encrypted watch-history chunks and DMs to reproduce/verify the
decrypt-cache wins and the DM-history bug, with before/after extension-call
counts.
