New `kiln-tui` crate (ratatui 0.30 / crossterm) that plays a board from a
.toml map named on the command line, letting the player walk around with the
arrow keys or hjkl. It depends only on kiln-core — the engine needed zero
changes, confirming it is genuinely UI-agnostic.
- Text rendering: each Glyph.tile index is reinterpreted as a character via a
CP437->Unicode table (cp437.rs); fg/bg map to ratatui Color::Rgb truecolor.
- render.rs BoardWidget: per-axis viewport that centers a small board and
scrolls a large one to keep the player visible.
- term.rs TerminalCaps: detects truecolor and Kitty keyboard-protocol support,
enabling the protocol when present (held-key repeat, modifier-only keys);
shows a rainbow "truecolor" badge in the bottom border.
- Input loop acts on Press and Repeat (continuous held-key movement) and
ignores Release.
Workspace: removed kiln-egui from members (files left untouched). Updated
CLAUDE.md and ARCHITECTURE.md to document the workspace split and kiln-tui.
