nav job mode: whole-menu titles as one nested list; Kimi Code API backend

Browse Source 
- translate.py: new "nav" job mode (Hello.modes opt-in) — the whole
  navigation hierarchy crosses as one nested Markdown list of pending
  titles, decomposed back by align_nav: item count/depth must match or
  the job is rejected wholesale (titles fall back to scoped jobs);
  items failing title checks individually are skipped to scoped jobs.
  Dispatched ahead of per-title jobs; a lone pending title stays scoped.
- article jobs carry the already-translated menu title and parent title
  as contexts, so the injected heading can match the menu while the
  model may adapt the in-article title to the content.
- llm_translator.py: nav mode + nav_prompt; article prompt takes the
  title/location context; API keys from per-provider env vars only
  (KIMI/MOONSHOT/OPENAI_API_KEY, each sent only to its own host;
  LLM_API_KEY generic) — no CLI flag, no config file; Kimi Code /coding
  endpoint support (sampling fields dropped, reasoning_effort from
  config, field-proven with k3-256k at low effort); errors include the
  response body; verbose per-job logging with the raw response incl.
  thinking (stripped from results); Kimi models announce all languages.

answer one job at a time — but speaks the "markdown", "article" and "nav"
job modes: fragments, whole pages and the whole navigation tree cross as
Markdown, and the server validates structure (blocks, fences, URLs,
placeholders, list shape) before storing.
The script figures out the LLM-side details itself: the endpoint shape is
autodetected (an ollama server answers /api/version and gets its native
/api/chat — its OpenAI-compatible /v1 ignores think:false, which hybrid
models need off; anything else gets /v1/chat/completions), and the
models need off; anything else gets /v1/chat/completions — a Kimi Code
/coding endpoint additionally has its sampling fields dropped, since it
fixes them internally and 400s otherwise, and gets reasoning_effort
from the config), and the
announced language capabilities follow the model family unless overridden
(--langs or config). Backend quirks (sampling, num_predict cap, think)
live in the config, not in the protocol.
(--langs). API keys come only from the standard per-provider environment
variables (KIMI_API_KEY, MOONSHOT_API_KEY, OPENAI_API_KEY — each sent
only to its own provider's host — and LLM_API_KEY for any other
OpenAI-compatible endpoint): never a config file on disk, never a CLI
flag visible in the process list. Backend quirks (sampling, num_predict
cap, think) live in DEFAULT_CONFIG, not in the protocol.
