Proposal: Move diff, bundler, and optimizer into CLI

[princerajpoot20]

As part of the 2026 community goals (more details here: asyncapi/community#3495), we conducted an audit of all repositories. The summary of the findings can be found here: asyncapi/community#3495 (comment).

As suggested by @deberg, we are proposing to move the diff, bundler, and optimizer repositories to the CLI repository.

Reference to the conversation:

• [2026 Goals][S1] Repository Audit & Consolidation (Targets O1, O2) community#3495

I am opening this issue to gather feedback and approval from the code owners of this repository regarding the proposal to move this repository to CLI.

Tagging all code owners for their feedback and approval.

I like this. AFAIK the primary usage of diff is through the CLI.

You have a "let's do this" vote from me.
