Open email context for agent, email search across All Mail, cookbook serve polish

- Agent: pass the open email reader (uid/folder/account/from/subject/body
  preview) on every chat submit so 'reply to this' / 'write email saying
  hi' route to ui_control open_email_reply with the right UID instead of
  inventing a new .md draft. Code-level enforcement (chat_routes strips
  create_document + send_email when active_email is set); cross-session
  active_doc_id is now trusted instead of being silently dropped.
  set_active_email/clear_active_email tool-layer helpers in
  tool_implementations.

- ui_control open_email_reply: optional body argument so the agent can
  open-and-write in one call; envelope now forwards uid/folder/account/
  body/panel through tool_output. Tool description sharpened and the
  parser rejects empty bodies on reply/reply-all (forces the agent to
  write rather than open an empty draft).

- Email library: search now runs against [Gmail]/All Mail when the
  current folder is INBOX (archived emails surface). Whirlpool spinner
  + 'Searching…' placeholder while in flight. Each search result is
  stamped with its source folder so clicks open the right email instead
  of whatever shares its UID in INBOX. Search no longer re-applies the
  same text pill locally (which only checks subject/from/snippet, never
  body) so body-only matches don't get dropped after IMAP returns them.
  Initial inbox load bumped 100→500.

- Email favorites: 'Favorite (pin to top)' / 'Unfavorite' in both the
  card menu and the open-reader more menu, backed by a new
  /api/email/flag/{uid}?on=true|false endpoint. Flagged emails always
  bubble to the top of the grid regardless of active sort.

- AI reply in doc editor: never overwrites existing draft text or the
  quoted history. AI suggestion is prepended; AI-generated 'On …
  wrote:' re-quotes are stripped so the original quote isn't visually
  edited.

- Cookbook serve: pre-launch GPU driver / has_gpu / install / version-
  floor checks (vllm minimax_m2 needs 0.10.0+, deepseek_r1 needs 0.7.0
  etc.) before the launch chain starts. Detect 'another model already
  running on this host' and offer Stop & launch (with graceful then
  force tmux kill helpers, port release wait). Per-vendor deep-link
  buttons (vLLM recipe / SGLang cookbook) with hardware hash. Backend
  picker is now a custom dropdown with accent-coloured logos for vLLM,
  SGLang, llama.cpp, Ollama, Diffusers; same glyphs added next to
  package names in Dependencies. Runtime-readiness note moved inside
  the panel (green when ready, red when missing) with an × dismiss.
  Esc collapses the expanded card; expanded card scrolls when it
  overflows; Trust Remote / Auto Tool / Reasoning Parser / Enforce
  Eager / Prefix Caching / Expert Parallel / Speculative / MoE Env on
  one row (Reasoning Parser auto-detected per model family).
  Dtype→Row 1, GPUs→Row 2 (rightmost). Removed redundant GPU 'auto'
  input — command builders read from the GPU button strip. Default
  cookbook open is Download tab.

- Cookbook hwfit: 'Model (latest)' / 'Model (oldest)' header sorts by
  release_date; release dates can be backfilled with the new
  scripts/backfill_model_release_dates.py and recipe metadata pulled
  with scripts/import_from_vllm_recipes.py against the upstream
  vllm-project/recipes catalog (vllm_recipe + min_vllm_version stamped
  on entries).

- Calendar: Quick add hint cycles a random Odysseus-themed example per
  open (wooden horse Friday, crew muster 10am daily, council on
  Ithaca, …). Typing a time like '11pm' in the event title updates
  the hero clock live.

- Doc editor: email-mode Reply button (sparkle icon, accent) opens the
  same Fast/Full + context popover the email reader uses; Ctrl+Alt+M
  toggles markdown preview.

- Memories panel: custom sort picker with per-option icons, default
  'Latest', visible Enabled/Disabled toggle text matching the section
  description style.
