Combines SkillsAnalytics (496 LOC) and SkillMarketplace (346 LOC) into
a single tabbed Skills Hub (770 LOC total, -9% code).
New structure:
- skills/shared.tsx: ProficiencyBadge, GapIndicator, constants (extracted)
- skills/OverviewTab.tsx: KPI cards, top 10 table, distribution chart, export
- skills/SearchTab.tsx: skill search + proficiency + availability filter
- skills/GapsTab.tsx: supply vs demand table with gap indicators
- skills/PeopleFinderTab.tsx: multi-rule AND/OR builder, chapter filter, export
- SkillsHub.tsx: tabbed container with URL-persisted tab state (?tab=)
Routing:
- /analytics/skills renders SkillsHub (was SkillsAnalytics)
- /analytics/skill-marketplace redirects to /analytics/skills?tab=search
- Sidebar: "Skill Marketplace" removed, renamed to "Skills Hub"
No API changes — reuses existing queries with conditional fetching per tab.
Full dark theme support on all components.
