🤖 Add workflow_dispatch test_filter to CI workflow (#423)

_Generated with `cmux`_

Allow manual CI workflow triggers to specify an optional test_filter
input that gets passed to both unit and integration test jobs. This
enables running specific tests via GitHub Actions UI without requiring a
full CI run.

## Usage

When manually triggering the CI workflow through GitHub Actions UI, you
can now specify a `test_filter` input:
- **Leave empty**: Run all tests (default behavior)
- **File path pattern**: `workspace` or `tests/specific.test.ts` -
matches file paths
- **Test name pattern**: `-t "pattern"` - filters by test description

## Compatibility

Both `bun test` and `jest` support:
- File path patterns as positional arguments
- `-t` flag for test name pattern matching

The filter is applied identically to both unit tests (`bun test`) and
integration tests (`jest`).
