fix(ci): lint must depend on ^build (resolve workspace dep types)

`@parking/server#lint` (tsc --noEmit) failed in CI with "Cannot find module
'@parking/db' / '@parking/shared'" + a cascade of implicit-any errors. Root cause:
the root turbo `lint` task had no dependsOn, but those packages expose their types via
"./dist/index.d.ts" — only present after their `build` runs. In a clean CI tree lint
ran before the deps were built, so tsc couldn't resolve them. Locally it passed only
because a prior `dist/` happened to exist. Make `lint` depend on `^build`, exactly
like `typecheck` and `test`. Verified from a fully clean tree (rm dist + .turbo +
*.tsbuildinfo): `turbo run build lint` → 14/14, 0 cached.
