fix(workflows): improve AUR SSH key handling and clone/push retries

This update enhances the workflow for interacting with the AUR by
adding robust error handling for SSH key retrieval and repository
cloning/pushing. It implements retry logic with exponential backoff
for both SSH host key retrieval and git operations, improving
resilience against transient network issues.

- Added retries for SSH key retrieval with exponential backoff
- Implemented retry logic for cloning and pushing to AUR repository
- Ensured script exits gracefully with error messages on failure

+## [2026.07.22] - 2026-07-22
+
+### Added
+
+- AI-assisted commit splitting for staged changes:
+  - analyze the staged diff and propose an ordered set of logical commits;
+  - generate an editable Conventional Commit message for every group;
+  - move files between proposed commits before applying the plan;
+  - create all accepted commits sequentially with **Commit all**.
+- Support for commit-splitting suggestions through OpenAI, Anthropic, and
+  custom OpenAI-compatible endpoints.
+
+### Changed
+
+- The commit-splitting dialog now explains why a plan cannot be applied and
+  clearly marks AI-generated commit messages as editable.
+- Safety checks prevent applying a stale plan after the staged files change
+  and reject files that contain both staged and unstaged changes.
+
+### Fixed
+
+- **Commit all** now passes a plain state snapshot to the commit workflow
+  instead of failing silently when cloning a reactive UI proxy.
+- Closing the active repository tab no longer allows an in-flight status or
+  fetch response to reopen and reactivate the closed repository.
