Hadron v0.27.0

Added

• Tokenized Theme System & Modern Presets (hadron-chamber):
  • Expanded ThemePreset and PresetPalette with Nord (Frost), Catppuccin (Mocha), and Gruvbox (Dark) curated themes alongside Obsidian, OLED, Midnight, and Tokyo.
  • Added semantic status tokens (success, warning, error, info, git_added, git_modified, git_deleted, window_border, selection_bg) wired to StatusPalette in ThemeDefinition and PresetPalette.
  • Added custom theme variant auto-numbering (next_available_theme_name, disambiguate_theme_names) so sequentially created custom themes display distinctly in Settings and /theme.
  • Upgraded /theme command and Settings overlay dropdown to list all 7 built-in presets and discover custom themes from ~/.hadron/themes/.
• Python ACP Bridge Automation & /bridge Command (hadron-gluon, hadron-chamber):
  • Implemented manifest-backed Python dependency tracking (BridgeManifest, evaluate_health, check_bridge_health, upgrade_venv) with SSOT package specifications (google-antigravity>=0.1.21, google-genai>=2.28.0).
  • Added /bridge [status | update] chat command to inspect and upgrade ACP Python virtual environments.
  • Wired automated bridge health evaluation and upgrade triggers into Chamber settings provider probe.
• UI Modernization & Token Migration (hadron-chamber):
  • Migrated hardcoded RGB values across widgets.rs, terminal.rs, and app/mod.rs to semantic theme tokens.
  • Enhanced chat capsule tabs with hairline borders on selection and subtle hover backgrounds.
  • Refined streaming draft cards with identity accent outlines and identity dots; added status halo borders to live action badges.
  • Added hairline border outlines to titlebar pills (update, repo monitor, GitHub monitor).

Fixed

• Changelog Overlay Modal Bounds & Text Wrapping (hadron-chamber):
  • Constrained changelog item text containers with flex_1 and min_w_0 to properly wrap multi-line notes instead of overflowing single-line.
  • Added line_height and flex_shrink_0 to bullet indicators and widened overlay modal to 580px (max_w(0.9)).
• Git Graph Rail Alignment on Commit Selection (hadron-chamber):
  • Applied .border_1().border_color(transparent_black()) by default across commit graph rows, branch rows, and expanded panels.
  • Kept layout border geometry constant and updated only border color on cursor selection, eliminating the 1px canvas horizontal shift.
• Diagnostics Hygiene in Quark Info Dashboard (hadron-chamber):
  • Removed duplicate DISPLAY & ENVIRONMENT and WORKSPACE & DISPLAY COMPATIBILITY blocks from Quark Info card.
  • Consolidated display server, layer shell, notifications, and graphics pipeline diagnostics under Settings → Environment.
