feat: Terraform intelligence, anti-flickering, and v2.2 release

- Official resource docs injection from registry.terraform.io (on-demand fetch + SQLite cache)
- Smart tfvars auto-generation from declared variables (tenancy_ocid, user_ocid, etc.)
- Multi-region provider: use var.region instead of hardcoded OCI config region
- RPC anti-cycle rule in system prompt
- System prompt auto-sync to DB on restart
- Fix UI flickering: animations scoped to tab switch only (tab-enter class)
- Terraform polling timeout increased to 60 min
- Terminal output updates without full page re-render
- Fix ${IC.bot} literal rendering in chat empty state
- Chat empty state icon scaled to 48px
- README updated to v2.2 with all changes
