GitButler 0.19.9のダウンロード

## TUI
- Significant performance improvements starting and navigating in the TUI (`but tui`)
- It's now more intuitive to create commits at arbitrary positions above/below other commits in the stack
- Toasts are now stacked vertically
- Adds support for creating a new branch from the `[unassigned changes]`
- Fixes an issue where squashing a commit without a message was causing additional whitespace to be added to the commit message
- The branch picker now (press `t` to open) now lists the `[unassigned changes]` at the top
- The branch picker now has key-binds `ctrl+n/p` to move up/down and `ctrl+[` to close the picker.
- Pressing `i` in commit mode will use inline reword to write the commit message, for cases where you don't want to open an editor.

## CLI
- `but status` - significant performance improvements
- When `but push` is executed, the app UI will be updated to reflect the new state
- Fixes a windows-specific issue that was causing the CLI to crash with a stack overflow.

## Fixes and Improvements
- Fixes a bug where in some cases a branch is not correctly detected as push-able
- Fixes a issue with forge integrations resulting in a "Command forge_provider not allowed by ACL" error
- Fixes a GitLab-specific issue where loading the integration would fail with "invalid type: string "...", expected internally tagged enum GitLabAccount"
- Fixes an issue where in rare cases of the remote tracking branch being deleted, committing locally would fail
- Fixes a UI issue causing a "null is not an object (evaluating 'u.close')" error popup
- It is now easier to distinguish different self-hosted forge integrations (instance URL is shown)
- Improved error handling when diffing deleted resources
