v3.0.4

Fixed

• Claude Code now drives on AWS Bedrock / Google Vertex. When the host has CLAUDE_CODE_USE_BEDROCK (or
  CLAUDE_CODE_USE_VERTEX) set, the claude-agent-acp adapter would fall back to the bare cloud alias
  claude-opus-4-8, which the provider rejects (400 The provided model identifier is invalid) — so
  delegate / consensus / doctor turns failed even though the seat was reachable. Rutherford now resolves a
  valid provider model id and injects it as ANTHROPIC_MODEL (plus ANTHROPIC_SMALL_FAST_MODEL when
  available) into the adapter's environment, so the SDK uses the real inference-profile id instead of the
  rejected alias. The id is resolved, in order, from an already-set ANTHROPIC_MODEL, a [agents.claude_code] model pinned to a raw provider id, ANTHROPIC_DEFAULT_OPUS_MODEL, then the env block of the host's
  ~/.claude/settings.json and <cwd>/.claude/settings.json (ANTHROPIC_MODEL then
  ANTHROPIC_DEFAULT_OPUS_MODEL). It is gated to the Claude Code adapter seat and to a Bedrock/Vertex host, so
  a normal API-key Claude Code and every other agent are untouched, and it never overrides an
  already-configured model. Works with zero Rutherford config when the id lives in settings.json.
• doctor recognizes the Bedrock "invalid model identifier" rejection. The model-unavailable classifier
  now matches "model identifier is invalid" / "provided model identifier", so a provider model rejection is
  reported as model_unavailable (the connection is healthy; the model/provider config is wrong) rather than
  a generic error.
