Replaces Croatoan (ncurses CFFI) with cl-tty (pure CL, no FFI) as the terminal rendering backend for the TUI channel.

Changes

passepartout.asd: swapped :croatoan → :cl-tty dependency
state.org: removed Croatoan from :use package list, theme-color returns hex strings
main.org: main loop uses with-raw-terminal + with-terminal + framebuffer-backend. Key dispatch via read-event with structured events. SIGWINCH resize handling.
view.org: all render functions rewritten to use cl-tty.backend:draw-text on framebuffer-backend instead of Croatoan window operations
render-styled: migrated from Croatoan add-string/height to cl-tty draw-text
Fixed: #\) character literal ambiguity in org source (CL reader vs paren counter)
Fixed: missing closing paren in defun on-key (the t clause last setf had 7 trailing parens, needed 8)

Verification

(ql:quickload :passepartout/tui) compiles cleanly under SBCL 2.5.2
All Croatoan references removed from tangled lisp files
cl-tty v1.0.0+ provides TrueColor, framebuffer, mouse, SIGWINCH, OSC 8, etc.

Prerequisite

Requires cl-tty v1.0.0+ at ~/quicklisp/local-projects/cl-tty

fix: close defun on-key with missing paren, complete cl-tty TUI migration 757541c83b

- Added missing closing paren for defun on-key in org/channel-tui-main.org
  line 616 (was 7 trailing ), now 8)
- Replaced #\) character literal with (code-char 41) to avoid reader
  ambiguity with paren-delimiter counting
- All 3 TUI org files tangled and verified compilable
- passepartout/tui loads without errors under SBCL 2.5.2
