Gives the daemon a public HTTPS hostname (`https://<random>.trycloudflare.com`)
so the in-browser player on torrentclaw.com plays cross-network without
Tailscale or port forwarding — the mixed-content block that was breaking
HTTPS-page → HTTP-daemon fetches is gone. Bytes proxy through CloudFlare,
never through TorrentClaw infra (preserves the aggregator legal posture).

New surface:
  • `internal/funnel/` package: subprocess wrapper + auto-download for
    cloudflared. Linux amd64/arm64/armhf/386 fetched from GitHub releases
    on first run, validated by ELF magic + size sanity, O_EXCL partial
    write so concurrent daemons don't clobber each other.
  • `unarr funnel on/off/status` cobra command (sibling of `unarr vpn`).
  • Daemon supervisor goroutine keeps cloudflared up across crashes + CF's
    ~6h Quick Tunnel rotation. Exponential backoff (2 s → 5 min). On exit
    the reported URL is cleared so the web stops handing out a dead host.
  • Wire: agent registers/syncs a FunnelURL field; web prefers it over
    Tailscale/LAN for in-browser playback (HlsStreamPlayer + Stremio
    addon).

Default ON for fresh installs (NAS/Docker get it without terminal-in);
existing configs that pre-date the feature stay off until the operator
opts in with `unarr funnel on`.

Docker image now bundles cloudflared (built per TARGETARCH via buildx).

Also fixed: libx264 'frame MB size > level limit' on anamorphic >16:9
sources. The level we hint to libx264 was derived from height alone,
which busted on 720p cinemascope (1728×720 = 4860 MBs > level 3.1's
3600). Bumped each tier: 720p → 4.0, 1080p → 4.1.

Version: 0.9.4 → 0.9.5.
