The previous commit referenced shared/ansi.ts, shared/format.ts, and shared/ctx.ts but those files were filtered by the default-deny .gitignore. Adding !/shared/ to the allowlist so the imports actually resolve in a fresh clone. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

/**

* Helpers for dealing with pi's ExtensionContext in the face of its

* "stale after session replacement or reload" semantics.
|
|
*
|
|
* Pi's ExtensionRunner throws when any captured ctx field is accessed after
|
|
* the runner has been torn down (on /quit, /reload, new session). This
|
|
* module provides a single guarded wrapper so every extension doesn't have
|
|
* to re-implement try/catch + null-on-shutdown patterns.
