feat(optimization): run knowledge searches through complete methods

[drewstone]

Summary

• run retrieval, full RAG, KB policy, and memory configuration searches through one complete OptimizationMethod
• retain only bounded exhaustive enumeration for small finite retrieval grids
• preserve independent train, selection, and final data, canonical candidate identity, resumable artifacts, parallel branches, cost limits, and compare-and-set activation
• remove knowledge coupling to proposer and local optimizer APIs
• update concise entry-point docs and the published agent-eval dependency

Verification

• pnpm lint: 176 files clean
• pnpm typecheck: pass
• focused optimization tests: 34 passed
• pnpm test: 440 passed, 10 skipped
• pnpm build: pass, including declarations
• pnpm verify:package: clean install, 5 imports, skill, CLI version, and re-pack
• deleted optimizer API scan: 0 references
• git diff --check: pass
• merge-tree against current origin/main: clean
