2.13.0

Added

• Central appearance settings (:settings or :appearance) for themes,
  automatic light/dark pairs, compact spacing, reduced animation and simple
  terminal status icons.
• Live theme preview across the actual workspace with reversible Escape and a
  compact F4 view; Light/Dark filters, favorites, recent choices, next and
  previous theme cycling, and undo to the previous theme.
• A visual theme customizer with live readability checks and private native
  JSON save/export.
• Four bundled light palettes (Paper Light, Solar Dawn, Nordic Snow, Sakura
  Light), giving 87 distinct theme choices with the offline catalog.
• :trial, a guided first task connecting harness discovery, setup
  diagnostics, project context, normal prompt execution and result review.
• :feedback, developer-reviewed local feedback bundles with bounded
  diagnostic metadata, error summaries and credential/path redaction. Bundles
  stay on your machine; nothing is uploaded.
• Follow terminal light/dark changes live through DEC mode 2031 colour scheme
  reports, and query the terminal background through tmux passthrough as well
  as directly.
• Warnings in the importer, CLI import and customizer when readability
  correction changes a colour.
• Letter-key alternatives in the gallery (e, w, f) and appearance screens (w)
  for terminals that intercept F3, F4 or Ctrl+S.

Changed

• New users without a saved theme follow the terminal (auto), using the
  reported background (OSC 11) and COLORFGBG by the xterm 16-colour
  convention; saved choices are unchanged and dark terminals still get the
  SuperQode palette.
• Query terminal colours on scheme change, or every 30 seconds when the
  terminal does not report changes, instead of every 3 seconds; check the
  active theme file once per second without resolving paths on every check.
• Dependency security updates across the lock file, including PyJWT, nltk,
  GitPython, mlflow, anyio, cryptography, urllib3, litellm, mcp, pillow and
  pyasn1.

Fixed

• Honour NO_COLOR and TERM=dumb in the TUI as well as the launch banner, and
  use 256-colour or 16-colour output when the terminal does not report
  truecolor.
• Resolve inline y/n/a approval keys before composer text insertion.
• Keep workspace approval, plan and navigation keys from acting behind modal
  editors and theme previews.
• Follow the terminal (auto) when saved theme preferences cannot be read,
  instead of failing on unreadable or deeply nested config.
• Windows path handling for long trial-context ids and file names Windows
  cannot create.
• Hold a DEC 2031 colour scheme report split across reads instead of leaking
  it as keystrokes, and turn mode 2031 off on every exit path.
• Wait for restored session state on startup instead of a fixed delay.
• Keep catalog themes visible while previewing without installing them, and
  record catalog light/dark appearance correctly.
• Return private copies of cached catalog themes so edits cannot alter the
  cache.
• Expand quoted file references so attachments with spaces and special
  characters resolve to the intended project file.
• Keep result and Activity text readable on light and dark palettes.
• Fall back to an exclusive file create when hard links are unsupported, so
  no-overwrite exports work on FAT and network filesystems.
