fix: correct replicated links and repository scope

[yada]

Summary

• exclude the specialized .project repository from all global replication
• align homebrew-tap with its Active / Tooling inventory classification
• avoid broken repository-relative links in the generic dependency policy
• correct malformed and non-canonical URLs in replicated documents

Validation

• parsed global-replicator.yml successfully as YAML
• confirmed every replication output includes EXCLUDED_REPOS
• confirmed the repository-dependent filenames are no longer Markdown links
• confirmed no hhttps:// URL remains
• git diff --check
• verified the replication run triggered by chore: align repository groups with subproject inventory #99 completed successfully
• verified all 33 generated MAINTAINERS.md PRs were merged
• confirmed the run still attempted .project and logged a push failure
• confirmed excluded demos and workshops did not regain stale workflows

Closes #100
