Summary

Centralize the catalog CLI default in DEFAULT_CATALOG_DIR and reuse it for both the curate and stale defaults and help text.

Why

The catalog path was repeated four times, so future changes could leave command defaults and help text out of sync. The constant remains the string ./data/catalog rather than a Path expression so this refactor preserves both argparse's default value type and the exact user-visible help text.

Closes #31

Validation

• uv run pytest tests/test_catalog_curation.py -q — 16 passed
• CLI parser check for both defaults and help strings — passed
• uv run ruff check --fix — passed
• uv run ruff format — 84 files unchanged
• uv run ty check — passed
• uv run pytest -q — 285 passed, 6 skipped, 5 unrelated local-platform failures: one test assumes /usr/bin/ffmpeg, and four require an ffmpeg build with the drawtext filter (the installed Homebrew ffmpeg lacks it)

Checklist

• I added or updated outcome-focused tests for changed business logic. (No business logic changed; existing CLI coverage passes.)
• I updated documentation for changed behavior, flags, formats, or requirements. (No user-visible behavior or documentation contract changed.)
• I ran uv run ruff check --fix, uv run ruff format, and uv run ty check.
• I ran the relevant pytest suite.
• I did not add recordings, generated media, credentials, private URLs, or runtime artifacts.
• I preserved stored-data compatibility or documented an explicit version change.

Thanks @bryanwhl, and welcome! Validated locally: full quality gate and test suite pass (293 tests), CI green on both Pythons. Special credit for the string-vs-Path reasoning in the description: you are right that Path("./data/catalog") would normalize away the ./ in the help text and make the argument's type inconsistent between defaulted and user-supplied runs. That is exactly the kind of trade-off note that makes a review fast. The honest report of the macOS-only test failures (/usr/bin/ffmpeg assumption, missing drawtext filter in Homebrew ffmpeg) is appreciated too; those are pre-existing platform issues, not caused by this change, and worth their own issue. Merging.
