factor-factory 1.0.2

Small post-v1.0.0 housekeeping pass before downstream showcase adoption.

Note on v1.0.1: the v1.0.1 tag was cut in the same development
window but its release workflow failed at the Set up job step
because astral-sh/setup-uv@v8 was used — upstream hasn't published
a v8 moving tag (latest moving tag is v7.6; only v8.1.0 exact
is available). No artifacts were published to PyPI or attached to a
GitHub Release under v1.0.1. Rather than rewrite history, v1.0.1 is
abandoned and this patch bumps to v1.0.2 with the exact-version pin.

Changed

• GitHub Actions pins bumped (.github/workflows/*.yml) to their
  latest majors to eliminate the Node.js 20 deprecation warnings
  GitHub surfaced on the v1.0.0 release run:
  • actions/checkout v4 → v6
  • actions/upload-artifact v4 → v7
  • actions/download-artifact v4 → v8
  • astral-sh/setup-uv v3 → v8.1.0 (upstream has not published a
    v8 moving tag yet — pinned to exact version)
  • softprops/action-gh-release v2 → v3
  • pypa/gh-action-pypi-publish@release/v1 stays (moving tag by
    design per the upstream maintainer's convention).

Fixed

• .gitignore adds .claude/scheduled_tasks.lock (MCP
  scheduled-tasks runtime-state file that was appearing as untracked
  on every developer clone with the plugin enabled).
