Assess Hono.js Rewrite ROI; No Code Changes

[Copilot]

The issue asks whether refactoring this project to Hono.js would provide meaningful benefit.
After reviewing the current architecture, the recommendation is not to perform a full rewrite now due to low near-term ROI versus migration risk/cost.

• What this PR changes

  • No repository code or tests were modified.
  • This PR records the technical assessment outcome only.

• Assessment outcome

  • Current backend is already cohesive on FastAPI + SQLAlchemy + Redis + APScheduler.
  • A move to Hono.js would be a cross-language rewrite (not an in-place framework swap), requiring reimplementation of routing, auth/middleware, data access, migration paths, and operational tooling.
  • For this workload, expected gains from framework replacement are unlikely to offset rewrite and stabilization cost.

• Recommended path

  • Keep FastAPI as the runtime baseline.
  • Improve incrementally where needed (query/caching/async job/observability hotspots).
  • Revisit Node/Hono migration only if there is a broader org-level Node standardization requirement.

Decision: Do not rewrite to Hono.js at this stage.
Scope: Assessment-only; no code changes.
