refactor(skills): compress 8 SKILL.md descriptions per writing-skills spec

Two issues fixed across personal skills:

1. Five skills had frontmatter > 1024 chars (spec limit per agentskills.io):
   - client-handover: 1920 → 924
   - doc: 1390 → 734
   - seo: 1378 → 885
   - geo: 1189 → 734
   - validate: 1050 → 742
   All now compliant.

2. Three orchestrators had workflow-summary descriptions that create
   "shortcut" risk per writing-skills CSO (Claude may follow the
   description instead of reading the full skill body, skipping steps):
   - ship-feature: "design → plan → implement (TDD) → review → finish"
     → "Use when shipping a feature end-to-end — needs… (9-step pipeline)"
   - init-project: "interview → design → scaffold → implement (TDD)"
     → "Use when initializing a brand-new project from scratch — needs…"
   - onboard: "detect archetype, install claude-config, run full audit…"
     → "Use when bringing an existing repo into the framework — needs…"

Descriptions now follow "Use when [triggers]…" pattern. Workflow detail
preserved in skill body where it belongs. Triggers consolidated and
trimmed of duplicates.
