Feature Request: Add Bun runtime support as an alternative to Node.js

Summary

Add official support for Bun as an alternative JavaScript runtime for building Obsidian plugins.

Motivation

• I already have Bun installed, but not Node

Proposed Changes

Minimal modifications to enable Bun support:

1. package.json: Update scripts (dev, build) to enable the possibility to use Bun instead of Node
2. .gitignore: Include bun.lockb.
3. README.md / AGENTS.md: Document Bun as an alternative option

Implementation

I'm going to prepare a PR with these changes: #172

I'm also building a real plugin using this Bun-enabled template. Will report results here.

Notes

• This should not replace Node.js - it's purely additive
• All existing documentation and workflows remain valid, although the idea is to document the possibility of using Bun instead of node
• Developers can choose whichever runtime they prefer
• The Obsidian API is unaffected since it runs in Electron, not Node/Bun

I would like to hear the team's thoughts on this! Happy to adjust the approach based on feedback.
