refactor(ci): cover all packages without polluting the test contract

The previous fix (b77f42e, reverted in f0cc614) added a test:integration
script to runtime and testing just so `vp run -r test:integration` would match
them — polluting every package's contract to satisfy the CI graph.

Restore the clean contract: normal packages (runtime, testing, cli) have only
a plain `test`; only runtime-tests splits into test:integration + test:pty.
The ci graph adapts instead of the packages:

  ci:test:misc        -> vp run --filter "@vue-tui/*" --filter "!@vue-tui/runtime-tests" test
  ci:test:integration -> vp run @vue-tui/runtime-tests#test:integration
  ci:test:pty         -> vp run @vue-tui/runtime-tests#test:pty

misc runs every normal package's own `test` (the glob auto-covers future
packages); runtime-tests' two suites are separate parallel branches, keeping
the slow PTY suite off the critical path. Verified `CI=true vp run ci` on a
fresh checkout: runtime (309) + testing (7) + integration (756) + pty (110),
PTY runs exactly once, exit 0.
