Federico Jaramillo Martinez 3742bcc962 refactor(plugin-api): trim plugin API scope to grounded capabilities

Builds on marcus's plugin-api-completeness work. Narrows the new plugin
surface to capabilities that expose real, otherwise-unreachable pi-web
functionality, and drops invented/duplicative surfaces:

Kept:
- files.writeFile / deleteFile / moveFile (genuine workspace mutation,
  federated, path-safe)
- prompt.insertText / getText / getSelection (editor state access)

Dropped:
- attachments.* (insertFileReference/getAttachedFiles/removeFileReference):
  getAttachedFiles invented a structured-attachment notion pi-web does not
  have and duplicated prompt.getText() + a regex with a false email-safety
  claim; insert/removeFileReference were thin sugar over readFile +
  insertText that plugins can compose themselves.
- prompt.onPaste / onKeyDown: an incomplete two-event hook system shaped
  around a single use case, overlapping the editor's native image-paste
  handling. Deferred until a real editor event/hook surface is designed.
- prompt.focus: redundant and buggier duplicate of the existing
  focusPrompt() (silently no-ops when not on the chat view). Focus stays
  as focusPrompt().

Security fix:
- deleteWorkspaceFile now resolves the parent via realpath + ensureInside
  before lstat/unlink, closing a symlinked-parent-directory escape that
  allowed deleting files outside the workspace (write/move already did
  this). Final path component is still not resolved, so deleting a symlink
  removes the link, not its target. Adds a regression test.

Docs and the registry test mock updated to match the trimmed surface.

patch

Add workspace file mutation (files.writeFile, files.deleteFile, files.moveFile) and prompt editor (prompt.insertText, prompt.getText, prompt.getSelection) APIs to the plugin system. File mutations work for local and federated machines, enforce workspace path safety, and auto-refresh the File Explorer.
