Verification baseline: fixture tests, CI, and operator docs

[amichne]

Summary

Build the verification and release baseline needed to keep semantic and packaging regressions out of the main branch.

Why

Current test coverage is still thin relative to the intended product shape. The visible server tests mostly exercise transport behavior against a fake backend, and the repo does not yet have CI smoke tests for real backend behavior or packaging.

Scope

• Add fixture-project contract tests shared across fake, IntelliJ, and standalone backends
• Add standalone bootstrap/compat regression coverage
• Add rename/reference/diagnostic integration tests on real fixture projects
• Add Linux and macOS CI smoke tests
• Add IntelliJ plugin verification and artifact-content checks in CI
• Add operator guidance for running the standalone backend on real repositories
• Update docs/remaining-work.md to reflect the current repo state

Done when

• Real backend behavior is tested against fixture projects
• CI catches bootstrap, packaging, and compatibility regressions automatically
• Operator docs exist for real standalone usage
• docs/remaining-work.md matches the current implementation status

Current read: issue #7 looks implementation-complete on branch amichne/complete-issue-7-tasks and PR #10. main still lacks these verification and documentation updates until that PR merges.

Closing as complete. The verification baseline work landed via PR #10, including shared fixture-project contract tests, standalone smoke and packaging coverage, IntelliJ plugin verification checks in CI, operator guidance for real standalone usage, and updated remaining-work documentation.
