refactor: move interaction handlers behind daemon facade

[thymikee]

Summary

• Closes refactor(daemon): move interaction and find routes behind the interaction facade #2178.
• Routes find and all interaction commands through src/daemon/interaction/index.ts, preserving request-chain lazy loading and route-owner metadata.
• Moves the 25 interaction production modules and their tests and fixtures under src/daemon/interaction/internal/.
• Adds structural red and positive-control coverage for retired handler paths and the request-handler eager closure.

Validation

• pnpm format:check, pnpm lint, pnpm typecheck, and pnpm build pass.
• pnpm check:layering passes all 186 structural tests and the full guard: 1,574 sources, zero value-import cycles, and zero forbidden logical imports.
• pnpm check:fallow --base origin/main passes with no issues in 96 changed files.
• pnpm depgraph:test, pnpm check:di-seams, and pnpm check:production-exports pass.
• Focused interaction suites pass: 40 files and 320 tests; native interaction contract passes 8 tests.
• pnpm check:affected --run passed 1,450 of 1,451 tests. The sole failure is an unrelated session-open test that only fails under broad related-test concurrency while signaling another worker process; the same test passes in isolation. GitHub CI remains authoritative.

Notes

• 96 files touched; scope remains within daemon interaction ownership plus routing and structural metadata.
• No docs or skills changed. No device session was opened.
