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

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.

Review package.json, .gitignore, README.md, and AGENTS.md first. Check how the dev and build scripts and lockfile handling should support Bun without replacing Node.js. Done means Bun is documented and usable as an alternative while existing Node.js documentation and workflows remain valid.
