[IGN-Styly]

Adds a plain Text node so terminal apps can render chat messages, lists, and input fields using the existing layout and renderer. Text clips by terminal cell width, keeps combining marks and wide glyphs intact, and filters control characters. Border titles now use the same safe text layout.

This supports the qmsg TUI. The crate and repository names stay fxcode; a rename to fxui can happen separately.

Validation: cargo test passes (11 tests; 2 optional mpv tests ignored). The existing media tests require docs/cars.mp4, which is absent from the repo; I supplied a generated one-second video locally for the test run. New tests cover Unicode clipping, control characters, and the right edge.

Used by qmsg PR #15. See the rendered chat demo (S9 file server; requires Tailscale). The consumer PR includes the matching before/after terminal captures.

📝 Walkthrough

The PR adds a public Text node with style and color options. The renderer paints text and titles with grapheme-aware clipping and terminal-cell width handling. The README documents text layout and handling.

Changes: Text rendering

Layer / File(s)	Summary
Text node API src/tree.rs, src/lib.rs	Node supports Text. The public Text type provides content, style, and color, and converts into Node. The crate re-exports Text.
Grapheme-aware painting Cargo.toml, src/renderer.rs, README.md	The renderer paints text and titles using grapheme display widths, filters control characters, clips to available cells, and handles wide-glyph continuation cells. Dependencies, documentation, and tests support this behavior.
