chore: add Pi extension config

[dipree]

Summary\n- Add Pi extension config for Entire hook integration\n\n## Tests\n- Not run (configuration-only change)

---

Note

Low Risk
Configuration-only agent hooks with best-effort subprocess calls; no changes to core Entire runtime beyond enabling Pi session capture.

Overview
Adds Pi integration so session and turn lifecycle events invoke entire hooks pi … for checkpoints and transcripts.

The checked-in extension at .pi/extensions/entire/index.ts matches what entire enable --agent pi installs: it forwards session_start, before_agent_start, agent_end, and session_shutdown with JSON on stdin (cwd, session_file, prompt), runs hooks via execFile with swallowed errors, and prepends GIT_TERMINAL_PROMPT=0 to bash tool commands so agent-driven git does not block on prompts.

A second file, .pi/extensions/entire.ts, implements a different contract (kebab-case subcommands like session-start / turn-start, session_id / session_ref, model_select, session_compact, and pi.exec with a 30s timeout). Only the entire/index.ts path is documented and used by the Entire installer; the sibling .ts file may be redundant unless Pi loads both.

OpenCode hooks on Pi CLI

High Severity

The new .pi/extensions/entire.ts invokes entire hooks pi with kebab-case names such as session-start, turn-start, and session-end, but the Pi agent only registers snake_case subcommands (session_start, before_agent_start, agent_end, session_shutdown). Unknown hooks return no lifecycle event, so this extension does not drive checkpoints or transcripts when it is the active handler.

Two Entire extensions auto-load

Medium Severity

Pi discovers both a top-level .pi/extensions/entire.ts and .pi/extensions/entire/index.ts as separate extensions, so both register the same lifecycle handlers. The incorrect root file still runs pi.exec on every event (up to 30s), duplicating work and risking slower or racy teardown alongside the correct index.ts hooks.

Invalid Pi hook subcommands

High Severity

The new .pi/extensions/entire.ts extension invokes entire hooks pi with kebab-case verbs like session-start and turn-start, and sends session_ref instead of session_file. The in-tree Pi agent only registers snake_case hooks and reads session_file in ParseHookEvent, so these invocations never produce lifecycle events.

Orphan extension outside installer

Medium Severity

Adding .pi/extensions/entire.ts alongside .pi/extensions/entire/index.ts introduces a second Pi extension that entire enable --agent pi never writes and UninstallHooks never removes (it only deletes the entire/ directory). Pi can auto-load both, and after uninstall only the broken top-level file may remain while AreHooksInstalled is false.

Pull request overview

Adds Pi agent hook configuration files under .pi/extensions/ to enable Entire’s lifecycle integration via a Pi TypeScript extension.

Changes:

• Add Pi extension at .pi/extensions/entire/index.ts that forwards Pi lifecycle events to entire hooks pi <event>.
• Add an additional Pi extension file .pi/extensions/entire.ts (appears to be an alternate/duplicate implementation).

File	Description
.pi/extensions/entire/index.ts	Pi extension that forwards Pi lifecycle events to the CLI’s entire hooks pi … handlers.
.pi/extensions/entire.ts	Additional Pi extension file that dispatches different (hyphenated) hook names; likely conflicts with the CLI’s expected Pi hook verbs.
