Add Indonesian (Bahasa Indonesia) language support in README

Proposal

I would like to propose adding Bahasa Indonesia (Indonesian) support to the README language list.

---

Why this matters

Bindu is a developer-focused project with global potential. Adding Indonesian support helps:

• Improve accessibility for Indonesian developers
• Expand community reach in Southeast Asia
• Encourage more contributions from Indonesian users

---

What will be added

• Add "Bahasa Indonesia" to the README language list
• (Optional) Add a short Indonesian description of Bindu in README

No changes to codebase or application logic are required.

---

✅ Scope

This is a documentation-only improvement and does not affect:

• Application logic
• API behavior
• Internal architecture

---

Willing to contribute

If this proposal is acceptable, I’m happy to submit a PR implementing it.

Thank you!
