FORNO-300: Skip premature enabling of AM via Block Notes

[iamchughmayank]

Fixes #

Proposed changes

Block Notes was hooking into the agents_manager_use_unified_experience filter to force-enable Agents Manager whenever Block Notes was active causing Agents Manager to load site-wide.

• Remove the enable_agents_manager_for_block_notes() function and its
  agents_manager_use_unified_experience filter hook
• Remove associated tests

Block Notes JS (block-notes.min.js) is self-contained and works independently of Agents Manager, consistent with how Image Studio operates.

Pull request overview

This PR removes Block Notes’ behavior that force-enabled the Agents Manager “unified experience” via the agents_manager_use_unified_experience filter, aligning with the goal of avoiding premature Agents Manager activation when Block Notes is enabled.

Changes:

• Removed the enable_agents_manager_for_block_notes() filter hook from the Block Notes extension.
• Deleted the associated unit tests that asserted the previous enablement behavior.
• Simplified test teardown by no longer clearing agents_manager_use_unified_experience filters.

File	Description
projects/plugins/jetpack/extensions/plugins/block-notes/block-notes.php	Stops Block Notes from enabling Agents Manager unified experience via a filter.
projects/plugins/jetpack/tests/php/extensions/plugins/block-notes/Block_Notes_Test.php	Removes tests for the deleted enablement function and drops related teardown cleanup.

[Copilot]

The PR removes the enable_agents_manager_for_block_notes() filter behavior (and its tests), but there isn’t a replacement regression test asserting Block Notes no longer enables Agents Manager’s unified experience. Consider adding a test that verifies no agents_manager_use_unified_experience filter is registered / apply_filters( 'agents_manager_use_unified_experience', false ) remains false when only Block Notes is enabled, so this behavior doesn’t accidentally reappear.
