Add Living Universe v0.2.2 server bridge overlay

[kaiwren986]

Summary

• add an installable, SHA-256-locked X Command server bridge for public X-Eve Living Universe v0.2.2 / EveJS v0.12.3.1
• install the same-origin UI/API listener, secure /x link flow, auth persistence, industrial and universe adapters, and Docker wiring
• add idempotent verification, automatic install rollback, exact uninstall restoration, and current public documentation

Validation

• npm run check (lint, production build, 20 tests, EveJS static build, bridge package integrity)
• npm audit --audit-level=low (0 vulnerabilities)
• clean public v0.2.2 copy: install and all three focused server verifiers passed
• native listener smoke: /health 200, / 200, bundled script 200, unauthenticated /api/v1/session 401
• Docker Compose parsed with EVEJS_X_COMMAND_ENABLED=true, bind host 0.0.0.0, and loopback port 26500
• uninstall restored all six shared files to their public baseline SHA-256 values and left zero bridge-owned files
• repeated install/uninstall is idempotent; unrelated local-config edits survive uninstall

Release posture

This should ship as a prerelease. The exact-version installer and focused bridge gate pass, but a full native/Docker real-client /x matrix and sustained combined soak have not yet been completed.

Port 26500 remains outside Play.bat readiness. A healthy Docker server is still recognized by game port 26000 plus proxy port 26002, avoiding the duplicate-native-server regression.
