Amin Borghei 9cb3eb9e5b feat(skills): add 25 skills across 3 new domains
Closes four coverage gaps identified by auditing the library against the
broader skills ecosystem. All content authored from scratch against
standards/skill-authoring-standard.md.

New domains:
- business-operations/ (6): capacity-planner, process-mapper,
  vendor-management, internal-comms, knowledge-ops, procurement-optimizer
- research-ops/ (4): market-research, product-research, clinical-research,
  research-finance — applied/operational, scoped distinct from academic
  research/
- markdown-html/ (4): md-document, md-slides, md-review, design-system —
  stdlib-only markdown to HTML, zero network calls

Additions to existing domains:
- engineering/ (5): write-a-skill, spec-driven-workflow, code-tour,
  agent-harness, cloud-security
- data-analytics/ (1): statistical-analyst
- project-management/ (2): team-communications, meeting-analyzer
- personal-productivity/ (3): capture, deep-work, reflect

44 new stdlib-only Python tools. Verified: 82 documented workflow blocks
execute, 71 exit 0 and 11 are documented CI gates firing on deliberately
flawed sample data. Statistical implementations validated against published
reference values (stats_core: 18/18; clinical sample-size matches textbook
n=93 and n=63; calibration Murphy decomposition reconciles to 0 delta).
Pattern 9 extraction test passes, including skills with local helper imports.
Zero oversized descriptions across all affected domains.

Wiring: plugin.json for each new domain, build_manifest.py DOMAINS,
marketplace registry, per-domain CLAUDE.md, root CLAUDE.md navigation map,
README counts (368 skills / 20 domains / 859 tools). Manifests regenerated.

inbox-triage was dropped from scope — personal-productivity/email-triage
already covers it and a near-duplicate would have been worse than the gap.
