v3.0.3's fix (#262) restored skills/ and .claude-plugin/ to the git
archive, which Claude Code needs for /plugin install. But
scripts/build-skill.sh uses the same archive to produce the claude.ai
.skill bundle, which must contain exactly one root SKILL.md and stay
under the 200-file cap.
Fix: after git archive, 'zip -d' strips both directories from the
.skill bundle. git archive output is unchanged (Claude Code still
gets the full tarball on /plugin install).

Wraps git archive with --prefix=last30days/ so the zip contains a single
top-level skill folder matching SKILL.md's name: frontmatter. Enforces:
- refuses to build with a dirty working tree (prevents shipping untracked changes)
- fails if zip exceeds 200 files (claude.ai's empirical upload cap)
- fails if zip contains more than one SKILL.md (avoids name: confusion)
Output at dist/last30days.skill (gitignored).
