chore: upgrade splinter to latest commit (#684)

## Summary
- Upgrade splinter vendor files to latest commit (b9de3a3) from
supabase/splinter
- Add two new security lint rules:
- `sensitiveColumnsExposed`: detects tables exposed via API with
potentially sensitive columns (PII, credentials, financial info) without
RLS protection
- `rlsPolicyAlwaysTrue`: detects overly permissive RLS policies using
`USING (true)` or `WITH CHECK (true)` for UPDATE, DELETE, or INSERT
operations
- Regenerated all codegen artifacts (rules, registry, categories,
configuration, docs)

## Test plan
- [x] `cargo clippy` passes
- [ ] CI passes
