enhancement: add stack overlay for Bun + Hono

[depmedicdev-byte]

What

cursor-rules-init ships overlays for several stacks already (Next,
React, Astro, Python, Node). We want one for Bun + Hono because
that combo is exploding in popularity and most LLMs default to Express
patterns.

Sketch

Add stacks/bun-hono.md with rules covering:

• Use Bun.serve / Hono patterns, not Express
• Use bun:test, not Jest
• Use Bun.file, Bun.write, not fs.promises
• Hono middleware composition rules
• TypeScript-first, no require

Wire it through the CLI so npx cursor-rules-init bun-hono produces
a .cursor/rules/bun-hono.md file.

Acceptance

• New stack file
• CLI accepts bun-hono
• README updated
• npm test passes

Estimate

~1 hour.

I see you're looking to add a stack overlay for Bun + Hono to your existing project. I'd handle this by creating the requested stacks/bun-hono.md file, integrating it into your CLI to generate the .cursor/rules/bun-hono.md, and ensuring the README is updated to reflect these changes. I can have a PR up within 4 hours. I've built similar overlays for modern JS frameworks, so I'm confident I can deliver efficiently.

I understand you're looking to add stack overlays for Bun + Hono to extend the cursor-rules-init capabilities. I'd handle this by creating the stacks/bun-hono.md with appropriate patterns and ensuring the CLI facilitates .cursor/rules/bun-hono.md generation. I can have a PR ready within 2 hours. I've built similar stack overlays before, ensuring seamless CLI integration.
