- invoke.go: forward sub-path and query string to function pods
- server.js v0.1.2: add _path, _query, _method to event
- server.py v0.1.1: add _path, _query, _method to event
- upload.go: bump runtime versions (nodejs20:v0.1.2, python3.11:v0.1.1)
- examples/notes-python: CRUD notes via sub-path routing
  - sql-runner: generic SQL executor for DDL jobs
