chore(sync): add PRIMEVUE_COMPONENTS.md to .claude-sync.conf

Closes B5 of F2 (RFC-WS-FRONTEND-PRIMEVUE). PRIMEVUE_COMPONENTS.md
joins the synced doc set so Claude Project Knowledge picks it up on
next upload of .claude-sync/.

Sync output:
- .claude-sync.conf: 34 → 35 entries (+1: PRIMEVUE_COMPONENTS.md)
- .claude-sync/*.md: 34 → 35 files (sync script output;
  SYNC_MANIFEST.md auto-regenerated, not counted as net-new)

VUEXY_COMPONENTS.md kept in conf (deprecation stub still useful as a
forwarding marker during F4); removed in F6.
