docs(README): List the 11 new MCP tools in the Tools table

why: The Tools table is the first surface readers hit on GitHub and
PyPI. After PR #11 added 11 new tools (snapshot_pane, paste_text,
select_pane, select_window, swap_pane, move_window, pipe_pane,
display_message, wait_for_content_change, enter_copy_mode,
exit_copy_mode), the table still showed only the pre-PR set, hiding
the new capabilities from readers who don't click through to the
docs site.

what:
- Session row: add `select_window`.
- Window row: add `move_window`.
- Pane row: add the nine new pane tools in a roughly semantic order
  (input → read → wait → navigate → mutate → scrollback/logging →
  destroy).
