v2.2.0 — Navigation mode, tool calling, and chat scrolling

Highlights since v2.1.0:

- Vim-style navigation mode in chat. Press Esc to switch from typing to a
  message cursor; i/a return to insert. j/k move between messages, h/l jump
  between user turns, gg/G snap to top/bottom, Space marks a message, y
  yanks the current (or every marked) message to the system clipboard, c
  clears marks, ? opens help, q exits.

- Tool calling. With "enable_tools": true in the AI config, the model can
  invoke in-app actions during a conversation. First-class tool:
  save_markdown — writes AI-generated content (summary, analysis, draft)
  to notes_dir as a clean standalone document.

- Chat scrolling. Ctrl+P/Ctrl+N, PgUp/PgDn, and mouse wheel now scroll the
  in-chat view; auto-stick-to-bottom resumes on new messages.

- /find renamed to /load. The command now reflects what it does (loads a
  file into chat context). /find still works as a silent alias.

- Discoverability for non-vim users: placeholder hint, first-Esc teaching
  status, unknown-key safety net, and ? for in-chat help.

- README and ROADMAP overhauled for clarity; roadmap extracted to its own
  file.
