reorg: tangle to XDG, remove stale lisp files, fix tui input

- Changed all 50 org file :tangle targets from ../lisp/ to
  ~/.local/share/passepartout/lisp/ (XDG data dir)
- Removed 49 generated .lisp files from project lisp/ directory
- Removed tests/system-integration-tests.lisp (generated)
- Removed lisp/*.fasl (compiled, stale)
- Updated core-manifest.org to tangle .asd to XDG root
- Remapped quicklisp symlink: local-projects/passepartout → XDG

TUI fixes in channel-tui-main.org:
- Removed with-raw-terminal (stty raw breaks fd 0 reads in this SBCL)
- Use cat subprocess + pipe for keyboard input (via :input :interactive)
- Blocking read-char on pipe with with-timeout 0.1s for daemon processing
- Key events queued via drain-queue alongside daemon messages
- Full dialog key routing (Escape, Up/Down, Enter, filters, Backspace)
- SIGWINCH resize handling
- Post-handshake backend-size re-query
- Daemon version in status bar (was v0.5.0 hardcoded)
- Handshake version stored in state, no add-msg
- :daemon-version and :size-queried in state plist
- view-status uses draw-rect for background
- Test section gated with #+passepartout-tests
