feat(release): attach native Arch package and repackage for AUR

Update release workflow to detect and attach the native Arch package.
Switch the binary AUR recipe to repackage the .pkg.tar.zst. Adjust
checksums and packaging steps so the output carries only the native
payload without bundling upstream package metadata.

- Attach the native .pkg.tar.zst to Gitea releases.
- Rework binary AUR recipe to extract usr from the native package.
- Update README to document using the native Arch package.

+## [2026.8.4] - 2026-08-15
+
+### Added
+
+- Branch folders now have a context-menu action for deleting all contained
+  local or remote branches at once. The top-level remote folder such as
+  `origin` is protected, while its nested folders remain manageable. The
+  currently checked-out branch is kept,
+  and individual failures are reported after the remaining branches have been
+  processed.
+
+### Changed
+
+- The Compare selector is fully localized in German and uses the same visual
+  language as the external-tool selectors for its fields, groups, typography,
+  and dialog surfaces.
+- Repository-tab close buttons are square and have clearer spacing, hover
+  behavior, and keyboard-focus feedback.
+
+## [2026.8.3] - 2026-08-13
+
+### Added
+
+- Configurable external tools for editors, diff viewers, merge tools,
+  terminals, and file managers, including automatic cross-platform discovery
+  and presets for VS Code, JetBrains IDEs, Beyond Compare, and other common
+  applications.
+- Repository and file actions for opening content in the configured external
+  application. Supported tools open in a separate window.
+- A choice between Gitty's internal diff/merge views and the configured
+  external applications.
+- Git Notes support for attaching editable notes to commits without rewriting
+  commit history, including fetch and push synchronization.
+- A command palette for quickly opening repository actions, files, and commits.
+- Complete branch-to-branch comparisons for local and remote branches. The
+  comparison dialog shows every changed file and its side-by-side diff.
+- Safe remote branch renaming from the branch context menu.
+
+### Changed
+
+- Redesigned the settings window with tool categories, detected applications,
+  preset dropdowns, and clearer explanations of where each tool is used.
+- Redesigned the history graph's branch presentation with compact labels,
+  hover details, cleaner flag connectors, and branch visibility controls.
+- Reduced the minimum width of the commit history panel so the workspace can
+  be resized more freely.
+- Local-only branches are now identified consistently in the toolbar,
+  repository summary, status bar, and commit graph. Their first push is labeled
+  Publish and configures the remote tracking branch automatically.
+- Git operations now run asynchronously to keep the application responsive
+  during slower repository commands.
+
+### Fixed
+
+- Closing supported external tools no longer reports their documented
+  comparison result codes as application errors.
+- External tools that otherwise reuse an existing process are explicitly
+  opened in a new window where supported.
+- Remote branch renaming uses an atomic push with lease checks, preventing an
+  existing destination branch or a newly changed remote branch from being
+  overwritten.
+
+## [2026.8.2] - 2026-08-10
+
+### Changed
+
+- History graph colors remain stable across parent lanes, making longer and
+  branching histories easier to follow.
+- Release artifacts are published to the matching Gitea release automatically
+  without creating duplicate assets.
+- Application shutdown now completes telemetry cleanup more reliably.
+
+## [2026.8.1] - 2026-08-04
+
+### Added
+
+- Paginated commit history that loads older commits on demand instead of
+  limiting the visible repository history to the initial page.
+- A dedicated file-history dialog opened from the explorer context menu.
+- Windows and Ubuntu release publishing plus improved AUR packaging workflows.
+
+### Changed
+
+- File history moved out of the permanent workspace panel into a focused,
+  larger dialog.
+- Dialogs close more consistently with the Escape key.
+- Arch Linux installation documentation now uses the `gitty-desktop` AUR
+  package.
+
+### Fixed
+
+- AUR SSH setup, package installation timeouts, and clone/push retries are more
+  robust in the release workflow.
