feat: add LOCUS and GAMA deterministic engine MCP servers - #4818

Both linked repositories exist and the artifacts are real. locus.exe is 2,572,288 bytes of genuine Rust build, with cargo registry paths and regex-automata-0.4.16 visible, a 13-subcommand CLI and 32 named rules. gama-mcp.cjs is 1,311,995 bytes of esbuild bundle around @modelcontextprotocol/sdk. This is not slop. Four facts then bear on it before more effort goes in.

The repository states in four places that it does not take this. CONTRIBUTING.md: "We don't accept: New server implementations". .github/pull_request_template.md: "We are no longer accepting PRs to add servers to the README." CLAUDE.md: "Not accepted: New server implementations …, README server listing changes." README.md:6 scopes the repository to "just the small number of reference servers maintained by the MCP steering group".

ADDITIONAL.md covers frameworks and resources rather than servers. Line 3 calls it "a curated collection of community-built frameworks and resources that simplify building MCP servers and clients". Its only two top-level sections are ## Frameworks and ## Resources. The ### For servers heading under Frameworks means frameworks for building servers. That is why this change had to invent a new top-level section.

The GAMA tool count is 48, not 49. Resolved every this.register({ manifest: … }) in the bundle, following const indirection:

register({ sites: 48
names extracted: 48 | distinct: 48
unresolved manifest consts: []
gama_/forge_ literals present but NOT registered: ['gama_benchmark', 'gama_body']

42 gama_* plus 6 forge_*. The GAMA README states no count; 49 appears only here.

The version numbers disagree with each other in both projects. LOCUS: tag v1.0.0, README v1.0.0, binary self-reports v1.6.0. GAMA: tag v1.0.0, README title v2.0.0, own table v1.0.0, bundle constants GAMA_MCP_SERVER_VERSION = "2.0.0" and GAMA_MCP_VERSION = "3.5.0".

Two smaller notes. Each repository tree holds LICENSE and README.md only, diskUsage: 3 KB, so nobody can read the #![forbid(unsafe_code)] claim. And LOCUS advertises protocol revision 2024-11-05, the first one ever published, hand-rolled rather than through an SDK, where the GAMA bundle carries 2025-03-26, 2025-06-18 and 2025-11-25.

Formatting is not the point here. The new section uses - where ### For clients uses *, but the file is already inconsistent: ## Resources runs 48 hyphens and no asterisks, and alphabetical order is already loose in three sections.
