Replace TypeScript sidecar with direct Claude CLI adapter

Major simplification: remove the entire TypeScript sidecar and per-adapter
packages. The Claude Code adapter now invokes `claude -p --output-format json`
directly, parsing the structured JSON result.

Deleted:
- sidecar/claude/ (package.json, tsconfig.json, src/index.ts)
- internal/adapter/claude/ (Go wrapper for sidecar)
- internal/adapter/codex/ (per-adapter package)
- internal/adapter/opencode/ (per-adapter package)

Created:
- internal/adapter/claude_cli.go — exec-and-parse adapter using `claude` CLI
  - Runs: claude -p --output-format json --permission-mode bypassPermissions
  - Parses: stop_reason, usage, cost, session_id from JSON output
  - CWD set to workspace directory
  - Inherits full parent environment (ANTHROPIC_API_KEY, GITHUB_TOKEN, etc.)
  - Uses locally-authenticated claude CLI credentials (~/.claude)

Simplified:
- ClaudeConfig: removed AdapterMode, SDKLanguage, SidecarCommand fields
- Factory: claude_code creates ClaudeCLI, opencode/codex use generic subprocess
- Doctor: checks for `claude` binary instead of tsx/node
- Dockerfile: debian:bookworm-slim runtime (no Node.js dependency)

This eliminates the Node.js/tsx runtime dependency entirely.
127 tests passing, all CI jobs expected green.
