• Move skill command handling to AgentSession, update docs

  - Skill commands (/skill:name) now expanded in AgentSession instead of
    interactive mode, enabling them in RPC and print modes
  - Input event can now intercept /skill:name before expansion
  - Updated extensions.md with clearer input event docs and processing order
  - Updated rpc.md: hook -> extension terminology, added skill expansion mentions
  - Added PR attribution to changelog entries for #761

• feat(coding-agent): add input event for extension input interception (#761)

  * 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

  instead of string[]. Extensions needing just names can use .map(t => t.name).

• feat(coding-agent): use built-in renderers for tool overrides without custom renderers

  When overriding a built-in tool (read, bash, edit, write, grep, find, ls)
  without providing renderCall/renderResult, the built-in renderer is now
  used automatically. This allows wrapping built-in tools for logging or
  access control without reimplementing the UI (syntax highlighting, diffs, etc.).

• Extensions: add pi.sendUserMessage() for sending user messages

  Adds sendUserMessage() to the extension API, allowing extensions to send
  actual user messages (role: user) rather than custom messages. Unlike
  sendMessage(), this always triggers a turn and behaves as if the user
  typed the message.
  
  - Add SendUserMessageHandler type and sendUserMessage() to ExtensionAPI
  - Wire handler through loader, runner, and all modes
  - Implement via prompt() with expandPromptTemplates: false
  - Add send-user-message.ts example with /ask, /steer, /followup commands
  - Document in extensions.md
