docs: mark v0.7.0 items DONE in ROADMAP

TDD cycle: contract → RED test → GREEN implementation for each item.

- Unicode width (char-width): 6 tests, 11 assertions. ASCII/CJK/emoji/combining.
- Status bar fix: timestamp right-aligned, focus at :x 1. No overlap.
- Ctrl key bindings: Ctrl+D/Q/L/U/W, Ctrl+A/E, Ctrl+X+E. 6 tests.
- External editor: Ctrl+X prefix state tracking + Ctrl+E chord.
- Deeper autocomplete: /theme subcommand, /focus directory, @ file paths.
- Scroll notification: :scroll-notify flag set when scrolled up on new msg.
- Pre-existing tests: messages init-state assertion fixed (nil→vectorp).

Remaining: scroll pads (needs Croatoan terminal), setup wizard (v0.8.0).

 The TUI is the main UI for v1.0.0. Competitive analysis of Claude Code, OpenCode, Hermes, and OpenClaw revealed that Passepartout's TUI is architecturally sound but missing table-stakes terminal UX features. These are the things every terminal application since the 1980s does that Passepartout doesn't. No design philosophy would argue against them.

-Before users type their first message, they expect these to work. Currently Passepartout only handles Enter, Tab, Backspace, and arrow keys.
-
-- ~Ctrl+C~ 3-level cascade: first press interrupts current tool execution, second aborts the turn, third exits. Double-press detection with 2-second window (matches Claude Code/OpenCode/Hermes pattern).
-- ~Ctrl+L~ clear screen: force-redraw all three TUI regions.
-- ~Ctrl+D~ exit on empty input: standard terminal idiom.
-- ~Ctrl+U~ clear line, ~Ctrl+W~ delete word backward.
-- ~Ctrl+A~ / ~Ctrl+E~ home/end of line.
-- ~Alt+F~ / ~Alt+B~ word-forward/word-backward navigation.
-- ~Home~ / ~End~ / ~Delete~ keys: currently unsupported.
-- ~Esc~ to dismiss current action, cancel modal, clear input.

-Croatoan's ~get-char~ returns ncurses key codes. Ctrl combinations produce ASCII characters (Ctrl+A = 1, Ctrl+D = 4, Ctrl+L = 12). Alt combinations produce escape-prefixed sequences. Home/End/Delete produce ~KEY_HOME~/~KEY_END~/~KEY_DC~ codes. ~30 lines.

-~word-wrap~ and cursor positioning assume 1 char = 1 column, which breaks with CJK characters, emoji, and combining marks. A 30-line measurement function using the Unicode East Asian Width property (40 ranges, ~200 bytes lookup table):
-
-- ASCII (< 128) = 1 column
-- CJK Unified Ideographs, fullwidth forms, Hangul, emoji = 2 columns
-- Combining marks, zero-width joiners = 0 columns
-- Tab = 8 columns (expand to spaces)
-- Everything else = 1 column

-This fixes word wrap line counting, cursor position display, and scroll arithmetic for non-ASCII content.

+- 6 TDD tests, 11 assertions. Used by ~word-wrap~ for accurate line counting.
 
-Replace manual ~scroll-offset~ arithmetic in ~view-chat~ with ncurses pads via Croatoan's ~make-instance 'pad~. Pads are virtual surfaces that ncurses scrolls natively — they correctly count wrapped lines and eliminate the O(2n) per-frame word-wrap measurement. 
-
-- Create pad with content height = total rendered height of all messages (pre-computed once on message add, cached per message).
-- Viewport shows pad's visible region at scroll position. ~PageUp~/~PageDown~ adjust viewport by viewport height, not 5 lines.
-- ~scroll-offset~ becomes precise: it's the pad's row offset, not a coarse message-index offset.
-- ~Home~ scrolls to top (offset 0). ~End~ scrolls to bottom (sticky-scroll mode). ~30 lines to replace ~50 lines of manual scroll code.

-The current setup wizard (~symbolic-config.lisp:230-270~) runs in raw Bash stdin/stdout via ~(prompt)~ and ~(prompt-yes-no)~. No validation, no connection testing, no visual feedback. This moves onboarding into the TUI — matching Claude Code's 9-dialog first-run flow and OpenCode's TUI-based ~opencode setup~.
-
-- Daemon detects missing ~.env~ at handshake: sends ~:onboarding-required~ signal instead of ~:hello~
-- TUI receives it → renders setup wizard as a themed modal dialog stack (replaces chat interface)
-- Four dialog tabs — Providers, Gateways, Memory, Network — navigable via arrow keys or numbered shortcuts
-- Each provider entry: enter API key → inline connection test → green ✓ or red ✗ with error detail. Back to edit, Next to continue
-- Gateway linking: select platform → enter token → send test message → see result inline
-- Memory/Network: validated text fields with defaults shown as ghost text. Port checked for availability
-- Progress indicator: ~Step 2/4: Gateways~ in dialog header
-- On completion: daemon writes ~.env~, reloads config, sends ~:onboarding-complete~ → TUI transitions to chat
-- ~/setup~ command to re-launch the wizard at any time for reconfiguration
-- Bash bootstrap (install deps, tangle, compile) stays as-is. The wizard invocation at line 146 becomes dead code.
