[BUG] generate:after hook is executed twice when using entrypoint with fs output #1993

Describe the bug.

When using the Generator API with:

• entrypoint set
• output = 'fs' (default)

The generate:after hook is executed twice.

This happens due to duplicate lifecycle invocation inside:

generator/apps/generator/lib/generator.js

The hook is triggered:

1. Inside handleEntrypoint()
2. Again inside executeAfterHook() (called from generate())

This causes duplicated side effects during the generation lifecycle.

Expected behavior

Lifecycle execution should be:

generate:before
generate:after

generate:after must run exactly once per generation.

Screenshots

How to Reproduce

1. Create a minimal local template with a generate:after hook that logs to console.

2. Create a minimal asyncapi.yaml file.

3. Use the Generator API with:

   • entrypoint set (e.g. index.js)
   • default output = 'fs'
   • forceWrite: true
   • install: false

4. Run the generation script:

   node repro.js

OR

Manually check : generator/apps/generator/lib/generator.js file
