docs: add Hindi developer setup guide

[arthuz-th]

Summary

Adds a Hindi developer setup guide for the documented ₹1,000 Hindi setup-guide bounty and links it from the README.

The guide is intentionally tied to the repository as it exists now. It covers:

• the current driver/source tree;
• Windows/WDK prerequisites;
• fork/clone/upstream/branch workflow using the canonical repository URL;
• the Linux/WSL CMake syntax-check path and cppcheck command used by CI;
• test-signing mode and its safety limits;
• an explicit warning that the currently documented Windows build/install/test scripts are not present in this tree;
• reproducible issue-report context and upstream-sync commands.

It also records the current-main syntax-check limitation at ebdbd2473456fcff033baa904ac3fe1f2e6e105b and links existing issue #7 instead of implying a contributor's environment is broken or opening a duplicate.

Closes #13

Verification

• git diff --cached --check passed before commit.
• The documented CMake command was run in WSL/Ubuntu against the current tree. It reaches compilation and then reproduces the already-reported format-string failures in Diagnostic format strings fail Linux syntax checks and omit numeric values #7; the guide explicitly documents that current limitation.
• Confirmed the guide links only repository paths/files that exist in the current tree.
• No driver code, runtime behavior, credentials, or payment information changed.

Bounty

CONTRIBUTING.md lists ₹1,000 — Documentation — Hindi setup guide — Reviewed and merged, with Wise available for international payouts. This PR is submitted for that documented bounty. Payment details can be supplied privately after eligibility/merge confirmation.

Development and translation were AI-assisted; the final technical claims were checked against the repository contents and commands were executed locally.

Thank you for clarifying the program change in e7e929f. I understand there are no cash bounties for new contributions.

One eligibility clarification for this existing PR: GitHub records its submission at 2026-09-09 05:22:33 UTC, before the policy-change commit at 06:14:03 UTC. The earlier CONTRIBUTING.md at ebdbd24 listed the Hindi setup guide at ₹1,000, subject to review and merge. Does the provision honouring reports submitted under the earlier terms also cover this pre-change documentation PR if you accept and merge it?

I am not assuming an award or requesting payment before acceptance. No payment/account details need to be posted here. The AI assistance and actual validation limits remain disclosed in the PR, and the contribution remains available for targeted documentation revisions in response to review.
