Use TypeScript project references for incremental builds (#7180)

* [AI] Fix duplicate typechecking by consolidating into lage

Previously `yarn typecheck` ran:
1. `tsc -b` (type-checks all packages via project references)
2. `tsc -p tsconfig.root.json --noEmit` (checks root bin/*.ts)
3. `lage typecheck` (runs `tsc --noEmit` per package - duplicate!)

Now it runs:
1. `tsc -p tsconfig.root.json --noEmit` (checks root bin/*.ts)
2. `lage typecheck` (handles everything via dependency ordering)

Changes:
- Remove `tsc -b` from root typecheck script
- Add `dependsOn: ["^typecheck"]` to lage config for correct ordering
- Change per-package typecheck from `tsc --noEmit` to `tsc -b` so
  declarations are emitted for dependent packages
