chore(repo): replace stale repository URLs with the canonical location

[karagozemin]

Problem

Package metadata, web navigation, and project documents still reference the previous personal repository URL instead of the current organization repository.

Task

Replace active references with the canonical Sub-Rosa-Issue/sub-rosa-issue GitHub URL. Do not rewrite historical examples or unrelated prose.

Acceptance criteria

• Active package and user-facing repository links point to the canonical repository.
• Relative documentation links remain relative.
• Documentation link checks and affected typechecks pass.
• No unrelated content changes.

Suggested implementation prompt

Find active references to the previous repository URL, replace them with the canonical organization repository URL, run link validation and affected typechecks, and keep the diff mechanical.
