feat(site): language coverage grid + README mirror for new metrics
- Add languages section with 68 cells colored by analysis tier (full AST + type inheritance, full AST + complexity, configurable plugin) - Compact tile size so the grid reads as a coverage map - Mirror edit-risk, score-drift, and bug-density capabilities into README to match the website - Bump README language count from 45 to 68

Tree-sitter built-ins get the full pipeline: function bodies parsed, cyclomatic and cognitive complexity, type inheritance (Python and TypeScript), and call graphs. The catalog plugins extract functions and imports via configurable prefix patterns, no AST. Every other metric on this page (edit-risk, score drift, bug-density, evolution, blast radius) works at every tier.
