Fono

Added

• Wyoming Home Assistant wire compliance. Frames now use canonical
  Wyoming framing (header version + data_length with a separate
  JSON data block; WYOMING_VERSION = "1.8.0"). info.asr is now a
  Vec<AsrProgram> per Home Assistant's all-services-as-arrays
  expectation, with placeholder arrays for tts/handle/intent/wake/mic/
  snd/satellite. Server queues transcribe arriving before
  audio-stop to match Home Assistant client behavior. New
  decode_pcm_le handles variable bit-width and multi-channel
  audio-chunk headers. New round-trip test
  server_accepts_home_assistant_transcribe_before_audio.
• Discovered-server tray UX. Tray gains a "Discovered Wyoming
  servers" submenu under STT backend; clicking a peer hot-reloads the
  daemon's STT config to point at the chosen remote. Daemon filters
  its own local instance out of the discovered list. mDNS advertiser
  uses enable_addr_auto() so A/AAAA records track network topology
  changes.
• Glibc symbol-version compat. Both the size-budget CI gate and
  the release build matrix now pin runs-on: ubuntu-22.04 (glibc
  2.35), so the shipped binary runs on Ubuntu 22.04+, Debian 12+,
  Fedora 36+, and any host with glibc ≥ 2.35.

Changed

• Canonical ship target is glibc-dynamic, not static-musl.
  release.yml builds x86_64-unknown-linux-gnu release-slim (it
  always did); the new Binary size & deps audit CI gate mirrors
  that target and asserts (a) size ≤ 20 MiB (measured at release:
  18.08 MB, ~2 MB headroom) and (b) NEEDED set is exactly libc.so.6 libm.so.6 libgcc_s.so.1 ld-linux-x86-64.so.2. Modern glibc (≥ 2.34)
  merges libpthread/librt/libdl into libc.so.6. Anything else (libgtk,
  libstdc++, libgomp, libayatana, libxdo, libasound, libxkbcommon,
  libwayland-*) fails the gate. ADR 0022 amended 2026-05-02; the
  original "no shared libraries" wording is superseded.
• CI job names rewritten for clarity: test (ubuntu-latest) →
  Build & test (ubuntu-latest); size-budget (release-slim) →
  Binary size & deps audit; cargo-deny → License & advisory audit; build ($target) → Release binary ($target).
• Server name "fono" → "Fono" for UI consistency in Home
  Assistant and elsewhere.

Deferred

• Static-musl single binary (Phase 2.4 of the binary-size plan).
  messense/rust-musl-cross:x86_64-musl ships a libgomp.a that is
  non-PIC (breaks -static-pie) and references glibc-only symbols
  (memalign, secure_getenv) plus a chain of POSIX symbols whose
  resolution depends on rust's link order. Eleven CI commits chased
  the chain (preserved in git log as 901e41d..29cc577, superseded
  in spirit by d2b54cb). Resurrection path: switch llama-cpp-2
  fork to llvm-openmp (libomp is PIC-friendly) or pin a PIC-built
  libgomp.a from GCC sources in our own minimal cross image. Not
  blocking the desktop ship target.

Fixed

• CI cache cross-glibc contamination. Suffix the
  Swatinem/rust-cache key with the runner image
  (size-budget-ubuntu-22.04, ${{ matrix.target }}-${{ matrix.os }})
  so cached build-script binaries don't migrate between runner-glibc
  generations and fail at execute-time with version 'GLIBC_2.X' not found.
