fix(themes): #52 broken/high-ROI fidelity fixes

Six per-theme defects: rose-pine btop rewritten to Dawn (was Main-on-Dawn,
invisible hi_fg); everforest + summer-night btop inactive_fg off main_bg;
vantablack role inversion (surface/overlay/muted + btop selection);
osaka-jade text↔subtext swap + warn→yellow; catppuccin-latte
mantle/accentAlt/ANSI axis; catppuccin Mocha btop (was Frappé). accentAlt
uses Latte mauve #8839ef, not the audit's pink #ea76cb (which fails the
3.0 contrast floor).

Worktree agent; diff reviewed + contrast conflict adjudicated. V0:
check-theme-contrast 24x7 all pass + flake check green. btop V2 render
pending (batched). Residual ansi[8]/ansi[3] drift noted.
