[P2] Remove the obsolete GitHub pagination rewriting claim #61

Recorded during review of main at a1eb305ccfa2f3fc8ddede4875765cf1b099bd2b. This issue records a finding only; no implementation changes were made or requested.

Finding

The README claims GitHub canonical numeric repository pagination links are rewritten to the current owner/repo path when the collection suffix matches. No such rewriting remains in production forwarding code: Link headers are passed through by the generic header filter. Tests instead cover canonical numeric paths in catalog metadata.

Evidence

• README.md:97
• src/proxy.rs:403
• src/catalog.rs:314

Desired outcome

Describe current generic Link forwarding and catalog handling accurately, without implying a GitHub-specific runtime branch.
