New zero-dependency workspace crate owning nebula_settings.txt path resolution, key semantics and the per-theme terminal color tables (background, light-theme foreground/ANSI-16 replacement, powerline slots 16..=23) - values transcribed verbatim from the legacy shell's theme.rs, which stays frozen per P4. The GPUI lab now honors the user's actual runtime intent: theme (SilverLight etc.) applied over toml colors in the same order as apply_term_colors, font family/size from the settings UI, default cursor shape/blink wired into the engine Term config, copy_on_select exposed for the next slice. Cargo.lock intentionally not committed: it currently carries the user's in-flight gpui-fork switch.
