The generator's `^description:\s*(.+)$` regex captured the block-scalar
indicator (">-") instead of the wrapped text, corrupting 43 descriptions in
index.json. Parse `>`/`|` block scalars properly and regenerate (0 broken).
Also refresh the count-update comment examples 754 -> 817.
- plugin.json was stuck at version 1.0.0 and count 753 — this is the file the
installer reads, so installs showed 1.0 everywhere. Bumped to 1.2.0 / 762.
- Update skill count to 762 across README (badge + 6 mentions), marketplace.json,
and plugin.json (754/753 -> 762 after merging PRs #70/#71/#81)
- update-index.yml: now auto-syncs the skill count into README.md,
marketplace.json, and plugin.json on every skills/ change (no more manual drift)
- sync-marketplace-version.yml: release now bumps plugin.json too (not just
marketplace.json) and pushes to main, so plugin version tracks the release tag
