Catch up to omnigraph-server 0.8.1

[ragnorc]

What & why

The SDK/MCP pin was a release behind. This bumps omnigraph.serverVersion and the package versions to 0.8.1 and re-syncs the vendored spec/openapi.json from the v0.8.1 tag. The tag's only spec change is the info.version string, so the generated types are unchanged — this is a pure version catch-up.

check-drift / check-versions / check-coverage and the full test suites are green. #15 (branch-merge deleteBranch support, draft pending the next server release) rebases on top of this.

Note

Low Risk
Version and metadata-only changes with no API or runtime behavior changes beyond reported version strings.

Overview
Aligns the TypeScript repo with omnigraph-server v0.8.1 after the SDK/MCP pin lagged one release.

omnigraph.serverVersion in the root package.json and @modernrelay/omnigraph / @modernrelay/omnigraph-mcp package versions move 0.8.0 → 0.8.1. Regenerated SERVER_VERSION and MCP_PACKAGE_VERSION in the version.gen.ts files match those pins. The vendored spec/openapi.json is re-synced from the server tag; the only spec delta in this bump is info.version, so generated API types are unchanged.

MCP server tests that assert initialize version and health sdkServerVersion are updated to 0.8.1.

Vendor the exact upstream spec payload

The v0.8.1 raw openapi.json tag is a compact 65-line file, while this diff keeps the previously formatted 2,568-line copy and only edits info.version; because scripts/check-drift.ts compares readFileSync(SPEC_FILE, 'utf8') directly against await response.text(), CI/release runs of pnpm run check-drift fail for this target version until the file is written exactly as pnpm run sync-spec would.
