Amr Gharbeia b9a4318ef8 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

* Channel Telegram
Extracted from gateway-messaging in v0.5.0. Isolated platform — Telegram-specific poll and send logic.
* Overview
The Telegram channel provides bidirectional communication via the Telegram Bot
API. Messages from Telegram chats are injected into the cognitive pipeline as
~:user-input~ signals with ~:source :telegram~. Outbound messages route through
the actuator registry when the pipeline targets ~:telegram~.
The channel uses two functions: ~telegram-poll~ (inbound sensor, getUpdates
with offset tracking) and ~telegram-send~ (outbound actuator, sendMessage).
Both retrieve the bot token from the credentials vault. The polling offset
(~:last-update-id~ in ~*gateway-configs*~) prevents duplicate processing across
poll cycles. HITL commands are intercepted before injection so approval flows
work identically across all channels.
** Contract
1. (telegram-get-token): returns the Telegram bot token from the vault
(via ~vault-get-secret :telegram~), or nil if not configured.
2. (telegram-poll): polls getUpdates with offset tracking (prevents
duplicate processing), injects each message as a ~:user-input~ stimulus
with ~:source :telegram~. Updates ~:last-update-id~ per cycle. Handles
API and JSON parse errors gracefully. HITL commands are intercepted
before injection.
3. (telegram-send action context): sends a message via sendMessage.
Extracts ~:chat-id~ and ~:text~ from the action plist. Logs send
failures without crashing the pipeline.
