harden: relay timeouts, DNS resolver reuse, cache hygiene + frontend polish

Server (relay/SSRF):
- Bound connect+TLS+request under CONNECT_TIMEOUT and body download under
  BODY_TIMEOUT so a stalling upstream can't pin a relay permit indefinitely
- Add inbound header_read_timeout to defeat slow-loris connections
- Allowlist relayed Content-Type (fall back to octet-stream) to block
  content-confusion from attacker-controlled stream origins
- Reuse one DNS resolver process-wide instead of rebuilding it per request
  (restores hickory's DNS cache; drops per-segment resolver setup)
- Probe cache: random per-process hash seed (DefaultHasher was deterministic)
  + bounded growth with expired-entry eviction
- Real Ctrl-C handler for a clean shutdown (honours the banner)
- Collapse the wrap_raw no-op alias into wrap

Frontend:
- Guide: visible focus ring tracking arrow-key navigation
- Player: buffering/tuning indicator while <video> is stalled
- prefers-contrast: more pass (lifts --ink-dim to meet WCAG AA)
- Service worker: date-stamped cache names so shell updates propagate

feat: Phase 1.5 — health prober, Oracle's Memory, off-thread EPG, PWA

Resilience + scale pass on top of the v1 core.

Stream health prober:
- New SSRF-validated /probe endpoint (HEAD -> ranged-GET fallback, 6s timeout,
  5-min TTL cache, concurrency-capped, no-store) + orb_probe_total metrics
- Front-end health.js: lazy bounded-concurrency probing (current + sampled
  channels, not the whole catalog), LIVE/DEGRADED/DEAD scoring, guide skull
  glyph, instant no-signal on zap to a known-dead channel

Oracle's Memory (memory.js):
- Session resurrection (last channel, volume, mute, theater/dim/ambient)
- Exponential-decay per-channel uptime history; pinning; dead-channel auto-skip

Off-thread XMLTV:
- lib/xmltv-parse.js (pure, hand-rolled scanner, no DOMParser/regex backtracking)
  run in epg-worker.js module worker; wired into the iptv-org provider
- Unit-tested in node: entity decode, TZ offsets, 20k programmes off-thread

Service worker / PWA:
- manifest.webmanifest + orb icons; sw.js (cache-first shell + hls.js,
  stale-while-revalidate for JSON-over-relay, never caches streams)
- CSP gains worker-src + manifest-src; relay sends no-store on /relay + /probe
  so the SW is the sole metadata freshness authority; webmanifest MIME fix

Docs: README de-emojified (title only) and reframed as a peer parallel build.

Verified: SSRF probes blocked, legit probe + cache, new headers present,
PWA assets served, parser tests 8/8, JS syntax clean, zero Rust warnings.
