v0.7.0

• feat(adapters): the self-host tier is real — a local adapter for any
  OpenAI-compatible server (Ollama, vLLM, LM Studio, SGLang, DwarfStar/DS4):
  user-declared capabilities and context window (the router's capability floor —
  never guessed), $0 default pricing (overridable, never invented), an explicit
  note when a server reports no token usage, and byte-exact tool-call ID replay
  promoted into the shared conformance battery for every adapter. New
  glam run --local / routing.localOnly fail loud rather than silently
  falling back to a hosted provider. Catalog gains ollama/vllm/lmstudio rows
  plus dwarfstar-ds4 and ornith-1.0-9b/35b with honest beta/unverified flags.
  Live-verified against a real Ollama daemon: keyless glam run tool
  round-trip at cost: $0.000000. (#25)
