userarena1002 is rebuilding Mike to run on Databricks

userarena1002 has dropped a complete second copy of Mike alongside the original, untouched, so both can move forward at once. The target is Databricks, an enterprise platform many large firms already use to keep data and AI workloads in-house and under governance. Rather than tweak the existing app, this rebuild reframes Mike from a multi-user product into a leaner tool: upload a document, get it reviewed, move on.

The accompanying plan is candid about what gets cut - logins, shared projects, cloud file storage, the open chat box, and document generation all go. What survives is the core: the engine that produces tracked changes on Word documents, plus the review timeline and edit cards. Worth noting that most of the actual review logic still returns canned results; this commit is the wiring and the blueprint, not finished features.
