TUI: 3-file split (model/view/controller)

- tui-model.lisp: defpackage, *state*, st/init-state, add-msg, event queue
- tui-view.lisp: view-status, view-chat, view-input, redraw (pure renders)
- tui-main.lisp: on-key, on-daemon-msg, daemon I/O, connect, tui-main
- ASDF updated to serial 3-file dependency
- Removed monolithic org/gateway-tui.org and lisp/gateway-tui.lisp
- Pre-commit hook: added 3 split files to croatoan exclusion
- core-skills: added 3 split files to skill loader exclusion
- Verified: LLM response arrives, /eval works, colors render
[no-verify: pre-commit hook SKIPped for TUI files]

 ***** DONE P3: Variable name drift normalization (out of scope for now) :backfill:
 CLOSED: [2026-05-03 Sun 11:50]

+***** TODO P4: Eliminate STYLE-WARNINGs from setup output             :cosmetic:
+SBCL emits ~25 STYLE-WARNINGs at boot due to forward references (function
+called before its =defun= appears in the file). Actual bugs (C/T, handler-case,
+bare =return=) are already fixed. Remaining warnings fall into two categories:
+1. Same-file forward references (reorder =defun=s to fix).
+2. Cross-skill references (inherent to skill architecture; suppress or accept).
+Reordering is mechanical but tedious — grep each file's =defun= list, compute
+topological order, move definitions down. Do not change function bodies.
