feat(system): enable window destroy capability and stabilize shutdown

Adds a new window capability to allow destroying the window.
It also changes shutdown handling in telemetry to avoid errors.

- Add core:window:allow-destroy to default capabilities
- Avoid shutdown errors by returning a pending promise in tracedInvoke
- Improve stability during shutdown for in-flight telemetry calls

 All notable user-facing changes to Gitty are documented in this file.
 
-The project uses calendar versions. Displayed release names use `YYYY.MM.DD`;
-package metadata uses the equivalent numeric form without leading zeroes where
-required by the package manager.
+The project uses calendar-style versions in the form `YYYY.M.PATCH`.
+
+## [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.
