- RegisterShortcut(ShortcutDef, handler) for global keyboard shortcuts
that fire across all non-modal app states (after ctrl+c, before
component dispatch). Handlers run in goroutines for safe blocking calls.
- ToolContext with IsCancelled/OnProgress for rich tool execution;
ExecuteWithContext on ToolDef takes priority over simple Execute.
- Source field on ToolCallEvent (currently "llm", forward-compatible
with future user-initiated tool calls).
- Fix missing //go:build ignore on context-inject.go.
- Update plan-mode.go to register ctrl+alt+p shortcut.
Extensions can now register an OnContextPrepare handler that fires after
the context window is built from the session tree and before messages are
sent to the LLM. Handlers receive ContextMessage entries with positional
indices and can filter, reorder, or inject messages. Original messages
referenced by index preserve tool calls, reasoning, and other complex
parts. New context-inject example extension demonstrates injecting a
local .kit/context.md file as an ephemeral system message every turn.
