chore: update development scripts for todo-worker and todo-worker-python

[andersonleal]

Summary

Improves the local development experience for the sample todo-worker (Node) and todo-worker-python examples by reloading the process when source files change.

• todo-worker: dev script now uses tsx watch instead of a one-shot node --import tsx run.
• todo-worker-python: adds the watchfiles dependency and runs the worker under watchfiles 'python -m src.main' in iii.worker.yaml so edits trigger a restart.

Type of change

• Bug fix
• New feature (developer experience)
• Breaking change
• Documentation update

Checklist

• Changes are limited to example worker dev workflows
• Python sample declares the new runtime dependency in pyproject.toml

Additional context

The workers repository uses main as the default branch (there is no develop branch here), so this PR targets main.

Uncommitted local edits (for example under image-resize/ or todo-worker/package-lock.json) were not included; the PR reflects commit 21b8a38 only.

Summary by CodeRabbit

• Chores
  • Implemented auto-reload functionality for local development environments. The Python worker and TypeScript worker now monitor file changes and automatically restart during development, improving the development workflow.

📝 Walkthrough

Walkthrough

The pull request adds file-watching capabilities to both Python and TypeScript worker development workflows. The Python worker now runs under watchfiles, and the TypeScript worker's dev script switches to tsx watch mode. A new watchfiles dependency is added to the Python project.

Changes

Cohort / File(s)	Summary
Python Worker Configuration todo-worker-python/iii.worker.yaml, todo-worker-python/pyproject.toml	Added watchfiles to dependencies and updated the worker start command to wrap python -m src.main with the watchfiles file-watching utility.
TypeScript Worker Configuration todo-worker/package.json	Updated the dev script to use tsx watch src/index.ts instead of node --import tsx src/index.ts, enabling automatic reloading on file changes.

Poem

🐰 A rabbit's wish, now code takes flight,
With watchfiles gleaming in the night,
No manual restart, no tedious wait,
Just save and run—oh, what a fate!
Both Python, TypeScript dance with glee,
Auto-reload sets us free! ✨
