Fix plugin version (1.0.0->1.2.0), sync skill count to 762, automate both

- 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

 A junior analyst knows which Volatility3 plugin to run on a suspicious memory dump, which Sigma rules catch Kerberoasting, and how to scope a cloud breach across three providers. **Your AI agent doesn't — unless you give it these skills.**
 
-This repo contains **754 structured cybersecurity skills** spanning **26 security domains**, each following the [agentskills.io](https://agentskills.io) open standard.  Every skill is mapped to **six industry frameworks** — MITRE ATT&CK, NIST CSF 2.0, MITRE ATLAS, MITRE D3FEND, NIST AI RMF, and the MITRE Fight Fraud Framework (F3) — making this the only open-source skills library with unified cross-framework coverage.  Clone it, point your agent at it, and your next security investigation gets expert-level guidance in seconds.
