fix(pyinstaller): filter non-existent dateparser cache files

[hobostay]

Summary

Fixed PyInstaller data collection for dateparser by filtering out non-existent cache files.

Problem

The dateparser timezone cache file (dateparser_tz_cache.pkl) is generated lazily on first use. In a fresh installation or CI environment, this file may not exist, causing collect_data_files() to fail tests when trying to bundle non-existent files.

Changes

1. src/kimi_cli/utils/pyinstaller.py: Added filtering logic to only include dateparser cache files that actually exist on the filesystem
2. tests/utils/test_pyinstaller_utils.py:
   • Updated snapshot to remove the non-existent deps/bin/rg entry
   • Removed unused platform import

Testing

• ✅ All tests pass (pytest tests/utils/test_pyinstaller_utils.py)
• ✅ Linting passes (ruff check)
• ✅ Type checking passes

🟡 Test snapshot still expects dateparser cache file that may be filtered out

The test snapshot at lines 31-33 unconditionally expects dateparser_tz_cache.pkl to be present in the datas list. However, the new filtering logic in src/kimi_cli/utils/pyinstaller.py:17 removes this entry when the file doesn't exist on disk. This means the test will fail in the exact scenario the PR is meant to fix (fresh environment / CI where the cache file hasn't been generated yet).

Root Cause

The production code at src/kimi_cli/utils/pyinstaller.py:17 filters out non-existent paths:

_dateparser_datas = [(src, dst) for src, dst in _dateparser_datas if Path(src).exists()]

But the test snapshot at tests/utils/test_pyinstaller_utils.py:31-33 still hardcodes the expectation that this file is present:

(
    f"{site_packages}/dateparser/data/dateparser_tz_cache.pkl",
    "dateparser/data",
),

When the cache file doesn't exist, the filter removes it from datas, but the snapshot still expects it → assertion fails. The PR was likely tested in an environment where the cache file happened to exist, masking this inconsistency.

Impact: The test test_pyinstaller_datas will fail in any fresh environment (e.g., CI) where dateparser_tz_cache.pkl has not been lazily generated, which is precisely the scenario this PR claims to fix.

(Refers to lines 31-33)

Prompt for agents

The test snapshot in tests/utils/test_pyinstaller_utils.py at lines 29-33 unconditionally expects dateparser_tz_cache.pkl to be in the datas list. Since the production code now filters out non-existent cache files, the snapshot needs to be conditional. Either:

1. Remove the dateparser_tz_cache.pkl entry from the snapshot entirely (if CI environments won't have it), or
2. Make the test dynamically build the expected list based on whether the file exists, similar to how the production code works. For example, compute the expected dateparser entries before the assertion and splice them into the expected list, or
3. Filter out dateparser entries from both actual and expected in the test (similar to how web/static entries are already filtered at line 26).
