Add crates/qbz-theme/src/custom.rs: the extended port of the Tauri "edit
theme colors" feature. A CustomThemeBase of 12 hand-picked semantic tokens
(surfaces, text, accent, status hues, border, favorite + is_dark polarity),
stored as opaque #rrggbb hex strings, derives the full ThemeColors contract.
Unlike Tauri (8 raw vars, no derivation, over the auto-theme only), editing a
base token now cascades: theme_from_base derives the accent triplet
(+0.10/-0.10 lightness, contrast-picked accent_text), the danger/warning/
success families (0.1/0.3 tints, polarity hover), muted/disabled text tiers,
border_strong, the translucent edges and the polarity alpha ramp.
Reuses the existing math instead of duplicating it: generator::{tint,
pick_btn_text_for_accent_set, ensure_text_contrast_target} are now pub(crate);
PaletteColor::shift_lightness and alpha_ramp are shared as-is. base_from_theme
is the inverse seed ("Start from current theme") and round-trips exactly for
any theme this module authored. Adds Rgba::to_hex. 9 unit tests (roundtrip,
polarity, determinism, accent-text legibility, malformed-hex fallback, JSON).
