chore: group all Vite+ packages on one Renovate policy

[fengmk2]

The vite catalog entry is an npm alias for @voidzero-dev/vite-plus-core, so it misses the preset's vite+ rule (0-day minimumReleaseAge, any-time schedule) and falls under the generic npm rule (3-day age, Monday schedule). Renovate then bumps vite-plus and leaves the alias behind: main already pairs vite-plus 0.2.4 with core 0.2.2, and #593 would widen that to 0.2.8 vs 0.2.2.

Add a repo rule so vite-plus, @voidzero-dev/vite-plus-*, and vitest share the vite+ group and the same age and schedule. vp pins the vitest override to the version bundled in vite-plus, so a lone vitest bump would desync that pin the same way; vite-task has no vitest today, making the match inert until it does. After merging, a Renovate run should fold the alias bump to 0.2.8 into #593.

Same fix as voidzero-dev/setup-vp#121 and voidzero-dev/setup.viteplus.dev#42, where Renovate folded the alias into the open update PR after the config merged. General write-up in voidzero-dev/vite-plus#2356; the preset-level fix Boshen/renovate#1 is still open, and this rule becomes redundant once it merges.
