Step 7.5b2: Spotify Connect zeroconf and login work (PCM counted only)

- Zeroconf on our httpd (GET/POST /spotify_info, form body URL-decoded)
  and _spotify-connect._tcp via our mDNS (VERSION, CPath, Stack TXT).
- Session task: waits for the app's login blob, connects with the
  user's client ID/secret and the configured bitrate (96/160/320 ->
  OGG_VORBIS_*), SpircHandler, events logged; cspot exceptions caught.
  Starts when source.mode is spotify/auto and credentials are set.
- bell::bellGlobalLogger was NULL: every CSPOT_LOG crashed the board
  right after addUser (Load access fault in Session.cpp:67 /
  LoginBlob.cpp:58). cspot/bell logs now go to esp_log (UART + syslog);
  signed CDN URL tokens are cut from the log.
- esp_audio_codec's own Vorbis decoder clashed with bell's Tremor
  symbols: CONFIG_AUDIO_DECODER_VORBIS_SUPPORT / SIMPLE_DEC_OGG off.
- status.spotify_state from the session (waiting / connecting /
  connected / login failed / error / disabled / no client credentials).
- Verified from a Mac: device appears, "connected as <user>", access
  token fetched with the user's client credentials, track info, audio
  key, CDN URL (the step broken upstream), PCM decoded. Without
  backpressure a track decodes in ~26 s (b3 feeds the ring).

Step 7.5b1: cspot (philippe44 fork) builds and links on the P4

- external/cspot: git submodule, pinned to philippe44/cspot 3010349
  (bell ed2d6e9); GPL-3.0.
- components/spotify: project component wrapping cspot. bell trimmed to
  what cspot needs (Tremor Vorbis; no codec wrapper, sinks, MQTT, web
  server, fmt, regex; cJSON from IDF). Xtensa biquad assembly filtered
  out (P4 is RISC-V). CMAKE_POLICY_VERSION_MINIMUM 3.5 for CMake 4.
- Patches in components/spotify/patches, applied at configure time:
  nanopb generator works with protobuf >= 5 (MakeClass removed);
  URLParser.cpp missing <cstdio>/<cstring> for GCC 14.
- CONFIG_COMPILER_CXX_EXCEPTIONS=y (cspot needs exceptions).
- spotify_init() only builds a LoginBlob (link check).
- CLAUDE.md: submodule init and IDF-venv Python packages for nanopb.
- Verified on board: "cspot linked: device "P4 AES67", zeroconf info 588
  bytes"; HLS still playing, PTP locked; image 1.83 MB (70% free).
