build(workspace): wire npm workspaces + shared tsconfig.base (ROADMAP P1)

Root package.json declares workspaces packages/* + apps/*; build/test/verify run kernel->memories->rules in dependency order. tsconfig.base.json factors out shared, behavior-preserving compiler settings; each package extends it and keeps its own module/moduleResolution + outDir/rootDir (kernel retains types:['node'] per the CI-red lesson). Single root lockfile resolves the missing-lockfile CI break (recon KER-02/MEM-005).

Baseline: 203 tests green (kernel 93, memories 35, rules 75). Save point: tag swarm-save-memory-os-20260616.
