v1.2.6

Axon v1.2.6

Axon v1.2.6 is a large architecture and polish release. It takes the work that
started as bug fixing and pushes it into the new production IDE structure:
extension packages, built-in contributions, a cleaner terminal workbench, a
faster modal system, and a more capable Source Control experience.

Architecture and Extension System

• Added the shared extension API package, extension manifest contracts, runtime
  contribution types, and example extension scaffolding.
• Moved the repository toward the new apps/, services/, packages/, and
  root-level extensions/ architecture.
• Added built-in extension metadata for themes, terminal, and other extension
  surfaces so the app can resolve contributions from manifests instead of
  hard-coded app fallbacks.
• Moved built-in theme source loading to extension manifests and kept the
  onboarding theme picker scoped to internal built-in themes.
• Improved the Extensions modal with clearer installed/downloaded states,
  marketplace metadata, GitHub links, and theme install handling.
• Documented the architecture migration in architecture.md.

Editor, LSP, and Navigation

• Fixed the save/dirty-file scroll jump so saving a buffer no longer moves the
  editor to the bottom.
• Fixed stacked Git/change decorations so repeated edits on the same range do
  not deepen the same yellow, green, or red paint.
• Restored command/control-click definition navigation while keeping Axon's
  tab-opening behavior ahead of Monaco's peek popup for cross-file jumps.
• Improved completion behavior for local exports, installed packages, external
  library imports, icons, HTML snippets, JSX/TSX web completions, and Tailwind.
• Improved hover behavior so TypeScript and Tailwind hovers do not stack in a
  confusing way.
• Fixed find behavior for command/control-F, including selected-text seeding
  and stable focus while editing the search query.
• Fixed breadcrumbs so symbol popovers open again and snippets are filtered out
  of breadcrumb labels.
• Split the main LSP feature module into focused facade, lifecycle, and request
  files so the LSP implementation remains maintainable.

Modals and Performance

• Refactored Settings into smaller sections and removed the old color override
  surface.
• Fixed Settings and Extensions modal slowness by reducing heavy render paths
  and keeping modal content scoped.
• Changed modal overlays from opaque full-screen covers to theme-aware
  translucent scrims.
• Removed backdrop blur from modal overlays because Electron compositing made
  it expensive on large windows.
• Made hand-rolled modals use the same modal feel as shared command modals.
• Kept workspace/folder loading surfaces theme-aware without reintroducing slow
  transparent skeleton overlays.

Source Control and Git

• Added a proper Source Control commit graph view with lanes, refs, hashes,
  authors, relative dates, and parent counts.
• Made graph loading explicit so Source Control opens quickly and only fetches
  commit history when the graph view is selected.
• Collapsed advanced Git workflow controls by default, loading branch, stash,
  conflict, and worktree data on demand.
• Kept the modal-level close button separate from the right-pane close button;
  the right-pane button now closes only the active file preview or graph view.
• Improved Source Control modal responsiveness by removing eager advanced Git
  queries from the open path.

Terminal and CLI

• Moved the built-in terminal workbench implementation under
  extensions/builtin/terminal.
• Added terminal contribution resolution so the app mounts terminal UI from the
  extension registry instead of importing old app-only terminal internals.
• Added shared platform panel types for terminal/output panel ownership.
• Rebuilt the dev axon CLI during npm run dev using a repo-local Go build
  cache.
• Split the axon CLI agent into prompt, composer, model picker, terminal
  helper, session header, and terminal UI modules.
• Added the full-width Axon terminal header, animated tagline, and improved
  slash-command picker.

UI and Theming

• Made sidebar file rows horizontally scrollable instead of truncating long
  filenames.
• Made sidebar context menus and tab popups theme-aware.
• Fixed modal placement and Zen mode chrome spacing around platform traffic
  light areas.
• Added custom scrollbars across editor surfaces.
• Increased the welcome tab built-in theme list to twelve internal themes.
