v0.17.3

Hotfix

• [x] packages/ui-components/src/FeatPowerModalFilters.test.ts: actually skip the system8 router checks when the sibling source isn't present. The previous attempt used describe.skip, but Vitest still executes the describe body callback during test collection, so the top-level readFileSync still threw ENOENT in CI. Now the file is read inside each it body, gated with it.skip, so collection no longer touches the missing path.
