feat: implement render engine with resolution decay (#39 ) 7e23d911a4

Implement Phase 3: render core engine with resolution-based decay and
default YAML rendering.

Core Features:
- Resolution decay model: child nodes receive resolution = parent × decay
- Epsilon threshold: nodes with resolution ≤ epsilon render as cas:<hash>
- Default YAML output format with 2-space indentation
- Cycle detection via visited set
- Floating-point tolerance for epsilon comparisons

Implementation:
- packages/json-cas/src/render.ts: Core render function
- packages/json-cas/src/render.test.ts: 38 comprehensive tests
- packages/cli-json-cas: ucas render command with --resolution, --decay, --epsilon flags
- CLI integration tests for render command

Tests: All 276 tests pass (38 new render tests, 3 CLI tests)
Build: Clean compilation with tsc
Lint: Passes biome check

Fixes #39
