Complete Skyrim Oghma retrieval and final catalog

[RANGROO]

Summary

• Ships the final Skyrim Oghma dataset and retrieval rules.
• Adds curated aliases, tags, NPC knowledge classes, and regional access.
• Uses the shared compact Oghma editor and audit presentation.
• Keeps custom articles intact across factory synchronization.

Factory and custom articles

• The packaged catalog remains the unchanged factory source of truth.
• Editing a factory article creates a custom override for that topic.
• Custom overrides survive catalog updates.
• Deleting an override immediately restores the factory article.
• Deleting all custom articles restores every overridden factory article in the same transaction.
• Catalog-backed topic names remain locked so overrides cannot detach from their factory source.

Retrieval and access

• Conversation results have priority, followed by exact location, region, and race context.
• One shared result budget defaults to 3 and supports 1 through 5.
• common is an article-only public-basic marker and is never assigned to NPCs.
• Specialist and negative classes control restricted knowledge.
• Article tags rank grounded topics; they do not create retrieval topics.

Validation

• Focused Oghma suite: 38 tests, 9,782 assertions passed.
• PHP lint, JavaScript syntax, JSON/checksum validation, and diff checks passed.
• No DLL or compiled artifacts.

Local deployment

• The earlier PR state is deployed to /var/www/html/HerikaServer.
• The latest reversible-override lifecycle is committed and validated but not deployed.
• No new browser or in-game test was run for the latest change.
