docs: de-vendor core examples (layer purity)

[chubes4]

Summary

Fixes #2375 — Data Machine core (generic layer) hardcoded saraichinwag.com as the worked example in docblocks and CLI help. RULES.md layer purity counts examples as violations: generic core must not name specific sites.

Replaced all saraichinwag.com occurrences with example.com in:

• inc/Core/Auth/AgentAuthorize.php — redirect-URI validation docblocks (~L412, L471-473)
• inc/Cli/Commands/AgentsCommand.php:996 — CLI ## EXAMPLES help text

Scope

• Docs/comments/help-text ONLY. No runtime logic changed — the redirect validation derives allowed hosts from network_home_url() and was already correct.

Verification

$ grep -ri saraichinwag inc/
(zero matches)

mention @Chubes — ready for review.
