[FEATURE] Hot Reload Support for Components (packages/components)

[lucasolopes]

Currently, when developing custom nodes in the packages/components directory, it is necessary to manually run pnpm build and restart the application for changes to take effect.

This process slows down development and reduces iteration speed for custom Flowise components.

Improvement suggestion:
Add support for hot reload, or at least an automatic watch mode, so that changes in .ts files under packages/components/src automatically trigger a rebuild — without requiring manual intervention.

This could be implemented using tools like chokidar, nodemon, or by integrating watchers into pnpm dev.

Expected benefits:

Faster custom node development.

Better experience for contributors and Flowise extenders.

Fewer issues caused by outdated builds.
