* feat(llm): add Hugging Face provider + selectable local Claude Code models

Adds two operator-selectable LLM backbones, wired through both the backend
and the War Room UI.

Hugging Face (OpenAI-compatible Inference Providers router):
- New `huggingface` provider reusing OpenAIAdapter (router.huggingface.co/v1)
- HF_TOKEN / HUGGINGFACE_API_KEY / HUGGINGFACE_TOKEN env resolution, config,
  setup wizard, CLI, factory, best-available, and .env.example
- Settings key card + 4 inference models in the picker + direct client routing
- Tests: src/__tests__/huggingface-provider.test.ts

Local Claude from Claude Code:
- Explicit "active backbone" pin in Settings so a connected agent (Claude Code)
  can be chosen; a pin outranks stored API keys in both the client resolver and
  mission dispatch
- Claude Code model picker (Account default / Opus / Sonnet / Haiku), threaded
  to the CLI's --model via an "agentId::model" encoding parsed by LocalAgentAdapter;
  requireLiveLocalAgent strips the suffix for connected-agent validation

* fix(llm): address PR #127 review — self-contained keyless path + centralized pin/model routing

Finding 1 — keyless mission path was not self-contained:
- Add the `local-agent` case to ConfigManager.getLLMConfig so provider:'local-agent'
  resolves (keyless, agent id — optionally "agentId::model" — in `model`) instead of
  hitting the default "Unknown provider" throw.

Finding 2 — inconsistent pin/model routing across dispatch surfaces:
- Centralize backend agent resolution in window.t3mpDispatchAgent (single source of truth).
  It honors an explicit pin OVER a stored API key and encodes the picked local model as
  "agentId::model" so it is never dropped.
- Route all three surfaces through it: mission dispatch, General (getGeneralConfig), and
  Admiral (_admBackbone). Previously General/Admiral only picked an agent when no key
  existed and sent the bare agent id, so a stored key overrode the pin and the selected
  Claude model was lost.

Tests:
- getLLMConfig('local-agent') regression coverage (self-contained keyless path)
- LocalAgentAdapter "agentId::model" passthrough reaches the CLI --model flag
- t3mpDispatchAgent behavior: pin>key precedence, model encoding, fallbacks (evaluated
  from the shipped docs/index.html)
- centralization invariant: mission/General/Admiral all route through t3mpDispatchAgent
- update the Op-Admiral keyless-routing static test to the centralized resolver
