Relative links in README tab resolve to gittensor.io instead of GitHub

[tmimmanuel]

Description

Relative links rendered in the README tab on the repository page incorrectly resolve to localhost paths instead of pointing to the corresponding GitHub URLs.

Steps to Reproduce

1. Open https://gittensor.io/miners/repository?name=bitcoin%2Fbitcoin
2. Navigate to the Readme tab
3. Click on any relative link in the rendered README (e.g. CONTRIBUTING.md, doc/developer-notes.md, or doc)

Expected Behavior

Relative links should resolve to the source GitHub repository:

• CONTRIBUTING.md → https://github.com/bitcoin/bitcoin/blob/master/CONTRIBUTING.md
• doc/developer-notes.md → https://github.com/bitcoin/bitcoin/blob/master/doc/developer-notes.md
• doc → https://github.com/bitcoin/bitcoin/blob/master/doc

Actual Behavior

Relative links resolve to gittensor.io paths:

• CONTRIBUTING.md → https://gittensor.io/miners/CONTRIBUTING.md
• doc/developer-notes.md → https://gittensor.io/miners/doc/developer-notes.md
• doc → https://gittensor.io/doc

Environment

• Browser: Chrome
• OS: Linux

Additional Context

This affects all relative links in README content. Absolute links (https://...) and anchor links (#...) are unaffected. The fix should rewrite relative hrefs to prefix them with the GitHub blob URL for the repository.

This also happens in Contributing tab.
