feat(cli): detached local up with readiness checks

[IniZio]

Summary

• add skytest local up -d detached mode that waits until local services and workers are ready
• keep skytest local up foreground behavior unchanged
• improve local lifecycle robustness checks used by CLI status/startup flows
• fix local seed script identifier bug to keep local setup stable
• update parser/tests/docs for new detached startup options

How To Launch SkyTest Locally

1. npm run skytest -- local setup
2. npm run skytest -- local up -d
3. npm run skytest -- local status
4. Open http://127.0.0.1:3000

How To Use Run Features

1. Run a single test case:
   • npm run skytest -- run test-case <DISPLAY_ID> --project-id <PROJECT_ID> --wait
2. Run a full project:
   • npm run skytest -- run project <PROJECT_ID> --wait
3. Optional file reporter output:
   • add --reporter file --report-dir <path>

Validation

• npx vitest --run apps/cli/src/cli-parser.test.ts apps/cli/src/commands/local.test.ts
• manual smoke for detached startup: npm run skytest -- local up -d --timeout-ms 180000
