Ed Zynda 9e1df38836 feat: add keyboard shortcuts, tool context, and ToolCallEvent source field
- 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.

//go:build ignore
// context-inject.go — Injects context from a local file into every LLM turn.
//
// Reads a context file (default: .kit/context.md) and prepends it as a system
// message to every LLM context window via OnContextPrepare. This is useful for
// injecting project-specific knowledge, coding standards, or RAG results that
// should always be visible to the model — without cluttering the session history.
//
// The injected message does NOT persist in the session tree (it's ephemeral,
// added at query time only). This means:
// - Changing the context file immediately affects future turns
// - No session bloat from repeated context injection
// - The model always sees the latest version of the context
//
// Configuration:
//
// KIT_OPT_CONTEXT_FILE — path to context file (default: .kit/context.md)
//
// Usage:
//
// kit -e examples/extensions/context-inject.go
// echo "Always use error wrapping with fmt.Errorf" > .kit/context.md
