feat: add pi CLI support and clis prompt terminal command

[ducphamhoang]

Summary

• Adds pi (https://pi.dev) as a fourth supported agent CLI tool alongside codex, claude, and gemini
• Adds clis prompt command for terminal-based agent interaction without Slack/Telegram
• Fixes process.execPath bug in runner launch that broke exit-record writing in nvm environments

Pi CLI integration

Session lifecycle (verified live against pi 0.75.5)

1. pi starts normally — auto-generates a session UUID
2. clisbot sends /session → pi outputs "ID: <uuid>" → captured via status-command mode
3. Resume: pi --session <uuid>

Pi's /session command outputs the current session ID, so it uses the existing status-command capture mechanism — no new infrastructure required.

Schema & config

• newSessionCommand field added to runner template types and Zod schemas, resolved through the standard template override chain
• pi registered as a valid agentCLITool with default template (create.mode=runner, capture.statusCommand=/session, resume via --session)

Session routing (runner-service.ts)

• Pi captures session IDs via /session (same pattern as codex/gemini), so it participates in standard live rotation — no special routing bypass needed
• retryFreshStartAfterStoredResumeFailure gate already handles create.mode=runner, so pi sessions survive crash recovery with no changes

Transcript normalization

• looksLikePiSnapshot: detects pi output; excludes bare > to avoid false positives with shell prompts
• shouldDropPiChromeLine: drops pi help-bar and working-status chrome while preserving Warning/Note content
• dropPiPromptBlocks: strips prompt echo blocks that pi re-emits before AI responses

Also fixes

• buildRunnerFromToolTemplate: preserve per-element resume args for non-codex runners (was incorrectly flattening arrays)
• Guard isPi detection against collision with Gemini output patterns

Tests: 54 chrome normalization tests, session routing tests, startup blocker coverage, schema defaults tests

clis prompt command

New clis prompt CLI command for sending a message to a running clisbot agent from the terminal and receiving the response on stdout — useful for scripting and local dev without a Slack or Telegram surface.

clis prompt --agent <id> --message <text> [--stream] [--json]

• src/control/prompt-cli.ts: runPromptCli using buildSteeringPromptText
• cli.ts / main.ts: prompt command added to CLI routing
• auth/resolve.ts: terminal:senderId principal resolved correctly
• channels/rendering.ts: plain-text renderer for terminal platform (no Slack/Telegram decorators)
• test/prompt-cli.test.ts: 12 tests covering auth principal, rendering, and help output

Standalone fixes

• process.execPath in runner launch (runner-exit-diagnostics.ts): bare node is not guaranteed to be in PATH inside tmux when using nvm. Using process.execPath ensures the exit-record writer uses the same Node binary running clisbot.
• shellQuote escape fix: single-quote escape was '\"'\"' (incorrect), now '"'"' (correct POSIX).

Test plan

• bun test test/text/text-cleaning-chrome.suite.ts — 54 pi chrome normalization tests pass
• bun test test/runner-service.integration.test.ts — pi session and routing tests pass
• bun test test/prompt-cli.test.ts — 12 terminal prompt tests pass
• bun run check — full typecheck + test suite passes
