Axon v1.2.8

Axon v1.2.8

Axon v1.2.8 is a stabilization release after the large v1.2.7 platform push. It
focuses on the places that matter when Axon is installed and used like a real
editor: packaged workspace handoff, Git decoration repainting, terminal link
stability, terminal output scheduling, workspace hydration, CI, and richer
theme syntax coverage.

This release includes the work after the v1.2.7 release-prep commit
9c5290f.

Packaged Workspace and Git Reliability

• Fixed packaged workspace handoff so axon . keeps the requested folder as the
  source of truth instead of briefly restoring an older closed workspace first.
• Reduced stale main-process workspace work so old indexing, watcher, and
  service tasks do not keep racing after a project switch.
• Coordinated workspace service hydration so the file tree can become usable
  while secondary services start in a cleaner order.
• Added a Git-only decoration heartbeat for packaged builds. Native watchers can
  miss edited-file change events even when new-file add events still work,
  which is why new files could turn green while modified files failed to repaint.
  The heartbeat refreshes Git status without enabling expensive full workspace
  polling.
• Kept the heartbeat scoped to the active watcher generation so closed
  workspaces cannot repaint the current sidebar.

Terminal Stability

• Stabilized confirmed terminal links by routing them through Axon's normal
  external-open path.
• Removed the xterm canvas renderer path that could crash React during workspace
  switches while disposing terminal sessions.
• Guarded terminal disposal so failed renderer cleanup does not take down the
  whole editor surface.
• Pipelined terminal renderer output so xterm writes are scheduled in batches
  instead of forcing every chunk through the slowest visible write path.

Empty Pane Imports

• Added drag-and-drop import support for empty panes.
• External files and media dropped into an empty editor area now go through
  Axon's existing validation/import path instead of becoming a separate
  one-off file loading behavior.

Extension Contracts

• Added debugger contribution contracts for launch configuration, breakpoint,
  variables, call stack, and debug-console style work.
• Added workspace-index extension contracts so future indexing/search features
  have typed extension-facing APIs.
• Kept these as contracts first so later debugger and indexing work can plug
  into the extension host without another architecture rewrite.

Syntax and Themes

• Added richer syntax maps to the remaining built-in themes:
  Anysphere, Apathy, Arctikai, Axon, Catppuccin, Solarized, and Zed.
• Stabilized YAML token coloring so YAML no longer falls back to plain text
  styling in common cases.
• Kept the TextMate/semantic decoration pipeline from v1.2.7 and expanded the
  theme data feeding into it.

CI and Build Validation

• Added GitHub Actions validation on every push.
• Added a main-process TypeScript check so missing generated config imports,
  preload/main regressions, and Electron-side type errors fail before release.
• Fixed dev asset loading and workspace hydration paths that were making local
  workspace switches feel slower or inconsistent.
