refactor: Restructure monorepo to apps/server/ and apps/web/ layout

Move src/ → apps/server/ and packages/web/ → apps/web/ to adopt
standard monorepo conventions (apps/ for runnable apps, packages/
for reusable libraries). Update all config files, shared package
imports, test fixtures, and documentation to reflect new paths.

Key fixes:
- Update workspace config to ["apps/*", "packages/*"]
- Update tsconfig.json rootDir/include for apps/server/
- Add apps/web/** to vitest exclude list
- Update drizzle.config.ts schema path
- Fix ensure-schema.ts migration path detection (3 levels up in dev,
  2 levels up in dist)
- Fix tests/integration/cli-server.test.ts import paths
- Update packages/shared imports to apps/server/ paths
- Update all docs/ files with new paths

 ## Key Rules
 
 - **Database**: Never use raw SQL for schema initialization. Use `drizzle-kit generate` and the migration system. See [docs/database-migrations.md](docs/database-migrations.md).
-- **Logging**: Use `createModuleLogger()` from `src/logger/index.ts`. Keep `console.log` for CLI user-facing output only.
+- **Logging**: Use `createModuleLogger()` from `apps/server/logger/index.ts`. Keep `console.log` for CLI user-facing output only.
-- **Hexagonal architecture**: Repository ports in `src/db/repositories/*.ts`, Drizzle adapters in `src/db/repositories/drizzle/*.ts`. All re-exported from `src/db/index.ts`.
+- **Hexagonal architecture**: Repository ports in `apps/server/db/repositories/*.ts`, Drizzle adapters in `apps/server/db/repositories/drizzle/*.ts`. All re-exported from `apps/server/db/index.ts`.
