Remove duplicate consoleErrorSpy declarations in 'command failure' and
'spawn error' tests that shadowed the outer beforeEach/afterEach-managed
spy. The inner declarations created a second spy on the already-spied
console.error, causing restore confusion and potential test leakage.
Implement all 5 CLI extension options for external orchestration:
- --port <port>: Start server on port, or attach if port occupied
- --attach <url>: Connect to existing opencode server
- --session-id <id>: Resume existing session instead of creating new
- --on-complete <command>: Execute shell command with env vars on completion
- --json: Output structured RunResult JSON to stdout
Refactor runner.ts into focused modules:
- agent-resolver.ts: Agent resolution logic
- server-connection.ts: Server connection management
- session-resolver.ts: Session create/resume with retry
- json-output.ts: Stdout redirect + JSON emission
- on-complete-hook.ts: Shell command execution with env vars
Fixes#1586
