feat(plugin): STT migration via audio_attachment_processor hook (L1-L6)
Closes Phase 2.A. STT now lives entirely in the plugin via the new public-API
method `api.register_audio_attachment_processor` added to the loader hook
(Rule 1 — extended API, no forced-internal). The fork patch stays minimal
(streaming.py gains a small loop that calls registered processors; loader
adds the 1 new method).

Plugin additions:
  routes/transcribe.py            POST /api/transcribe + audio_attachment_processor
                                  - _external_stt_transcribe: multipart POST to STT endpoint
                                  - _handle_transcribe: one-shot transcription route
                                  - _transcribe_audio_attachments: voice-message processor
                                  - _parse_multipart_file: stdlib email-based multipart
                                    (Python 3.13 dropped cgi per PEP 594)
  tests/unit/test_transcribe.py   8 tests (register, processor, route, multipart parser)
  tests/evals/test_features.py    + 1 eval (audio processor signature contract)

Config (read at call time, never persisted):
  HERMES_WEBUI_STT_URL  external STT endpoint (OpenAI or WhisperX shape)
  HERMES_WEBUI_STT_KEY  optional bearer token

CONNECTION-MAP regenerated: 9 public-API · 0 forced-internal · 1 frontend.
20/20 tests PASS.

Loader API extended in hermes-webui (next commit there) — 7th method:
register_audio_attachment_processor. Streaming.py gets a small loop that
calls registered processors before _build_native_multimodal_message.

"""svrnty-hermes-webui-plugin — entry point.
Called by hermes-webui's plugin loader at startup (after the env var
HERMES_WEBUI_PYTHON_PLUGIN points the loader at this module).
The loader passes a single `api` argument exposing 6 methods (see CLAUDE.md +
protocol PRD §5.1). This module's job is to wire every route + static dir +
asset injection that defines the Svrnty surface on hermes-webui.
Keep this file thin. Route logic lives in `routes/<feature>.py`. Static lives
in `static/`. The map of every upstream dependency is in CONNECTION-MAP.md
(AST-generated by scripts/ast-connection-map.py).
