fix(coding-agent): pass host keybinding hints to extension renderers (#11630)
Fixes #4748.

## Problem

Extensions that import `keyText`/`keyHint` from
`@earendil-works/pi-coding-agent` can resolve their own copy of the
package (their own `node_modules`, or the bundled `cli.js` vs
`dist/index.js`). That copy's keybindings are never set by the host, so
it falls back to a manager with only `tui.*` bindings, and
`keyHint("app.tools.expand", "to expand")` renders as ` to expand`.

## Change

The host passes its own `keyText` and `keyHint` to extension renderers,
the same way it passes `theme`:

- `ToolRenderContext` (`renderCall`/`renderResult` context):
`context.keyHint(...)`
- `MessageRenderOptions` and `EntryRenderOptions`:
`options.keyHint(...)`

All three extend a new exported `KeybindingHints` interface. The docs
and the `debug-provider` example now use the injected functions and warn
against importing them in renderers.

Not done:

- Moving the `pi-tui` keybindings singleton to `globalThis`. Per the
discussion in #7011, extension-facing state should be host-owned and
passed through the extension API instead of shared through process-wide
module state.
- `ctx.ui.keyText`/`keyHint`. No reported case needs them outside
renderers, RPC and print modes never install app keybindings, and adding
them to `ExtensionUIContext` would break SDK hosts that implement it.

## Tests

- `test/extension-keybinding-hints.test.ts`: tool, message, and entry
renderers format a user-overridden `app.tools.expand` binding.
- `npm run check` passes.

Examples

Example code for the pi-coding-agent SDK, process integration, and extensions.

CLI integration

rpc-client.ts uses the typed RpcClient to run Pi in a child process, stream events, and wait for the run to settle.

Build the coding-agent package before running it from a repository checkout:

node examples/rpc-client.ts "Explain this repository"

extensions/

Example extensions demonstrating:

  • Lifecycle event handlers (tool interception, safety gates, context modifications)
  • Custom tools (todo lists, questions, subagents, output truncation)
  • Commands and keyboard shortcuts
  • Custom UI (footers, headers, editors, overlays)
  • Git integration (checkpoints, auto-commit)
  • System prompt modifications and custom compaction
  • External integrations (SSH, file watchers, system theme sync)
  • Custom providers (Anthropic with custom streaming, GitLab Duo)
