Quickstart bun

[bradleyshep]

Description of Changes

Adds a Bun quickstart template and documentation for SpacetimeDB.

Template (templates/bun-ts/)

• SpacetimeDB module with TypeScript (spacetimedb/src/index.ts)
• Bun client with interactive CLI (src/main.ts)
• Uses Bun-native APIs (Bun.file(), Bun.write()) for token persistence
• Uses Bun's native WebSocket and TypeScript support
• Pre-generated module bindings in src/module_bindings/

Documentation (docs/docs/00100-intro/00200-quickstarts/00250-bun.md)

• Step-by-step quickstart guide following existing pattern
• Covers project creation with spacetime dev --template bun-ts
• Explains project structure and Bun-specific client code
• Documents environment variable configuration (SPACETIMEDB_HOST, SPACETIMEDB_DB_NAME)
• Highlights Bun-specific features (native WebSocket, built-in TypeScript, .env support)

Consistency

• Environment variables follow the same HOST/DB_NAME naming convention as other quickstarts
• Documentation structure mirrors Node.js quickstart
• Interactive CLI mirrors Node.js template behavior

API and ABI breaking changes

None.

Expected complexity level and risk

1 - Additive change only. New template and documentation, no modifications to existing functionality.

Testing

• Run spacetime dev --template bun-ts my-bun-app and verify app starts
• Verify SpacetimeDB connection works via WebSocket
• Test adding a person via the interactive CLI
• Verify real-time subscription updates appear in client
• Check documentation renders correctly in Docusaurus

This largely looks good. I left two nit comments which I'd like to address before merging if you agree.

One major comment though, have you tested/walked through the quickstart yourself? I see that this uses bun native websockets, I'd like to make sure that works for sure.

Yep, I have tested the quickstarts and they work on my end.
