* feat(coding-agent): add input event for extension input interception Extensions can now intercept, transform, or handle user input before the agent processes it. Three result types: continue (pass through), transform (modify text/images), handled (respond without LLM). Handlers chain transforms and short-circuit on handled. Source field identifies origin. * fix: make source public, use if/else over ternary * fix: remove response field, extension handles own UI

* Input Transform Example - demonstrates the `input` event for intercepting user input.
|
|
*
|
|
* Start pi with this extension:
|
|
* pi -e ./examples/extensions/input-transform.ts
|
|
*
|
|
* Then type these inside pi:
|
|
* ?quick What is TypeScript? → "Respond briefly: What is TypeScript?"
|
|
* ping → "pong" (instant, no LLM)
|
|
* time → current time (instant, no LLM)
