* chore: declare GreptimeDB Enterprise License for enterprise-gated sources
The `enterprise`-feature-gated sources (triggers, mito2 extension) were
excluded from the Apache-2.0 header check but carried no license of their
own. Declare a separate GreptimeDB Enterprise License and enforce it.
- Add LICENSE-ENTERPRISE (open-core split; core stays Apache-2.0).
- Add an Enterprise License header to each enterprise source file.
- Add licenserc-enterprise.toml and a second hawkeye step in CI to enforce
the Enterprise header on exactly those files.
- Cross-reference the two complementary file lists; document the layout in
licenses/README.md and the README License section.

* chore: reference per-customer Enterprise Agreement instead of a terms URL
There is no public enterprise-terms page; each customer signs an individually
negotiated agreement. Point the license at a "separate written commercial
agreement with GrepTime Inc." and direct readers to the existing contact page.
