fix(tui): make the color palette theme-agnostic

Browse Source 
The palette used absolute 256-color indices (`38;5;252`, `48;5;236`, …)
that terminals never remap to the active scheme: near-white body text
vanished on light backgrounds and fixed dark bubble fills put default
foreground text on dark blocks. Rebuild it from the standard 16-color
ANSI foregrounds plus SGR attributes, keep body text on the terminal
default foreground, replace filled background bubbles with foreground-only
left-gutter bars, and use reverse video for the active selection so every
grouping reads on any color scheme.

Startup fails before mounting when either process stream is not a TTY. While waiting for its configured agent, the front door also observes retained and live `agent/start-failed` notifications; a matching failure is written before fullscreen mode starts and exits with status 1 instead of leaving a blank terminal. Disposal stops loaders, rejects pending questions, drains terminal input, restores terminal state, unregisters event listeners and the user-interaction provider, and never exits a replacement process during HMR.
## Color
The palette uses the standard 16-color ANSI foregrounds and SGR attributes, which every terminal remaps to its active color scheme, so it stays readable on light and dark backgrounds alike. Body text keeps the terminal's default foreground rather than a fixed shade. Grouped regions (user prompts, tool cards) use a colored left-gutter bar instead of a filled background block, and the question overlay's active row uses reverse video; both are foreground-only, so they never collide with the terminal background. Set `color: false` to strip all styling.
