fix: gebruik theme_session_completions voor learnDone op dashboard

getLearnDone was een deprecated stub die altijd false teruggaf nadat
de learn_progress-collectie is gedropt. Hierdoor toonde het dashboard
permanent 'Complete your theme session first', zelfs als de theme
session al voltooid was, en werd cycle progress nooit opgeteld.

Alle drie call-sites vervangen door getThemeSessionCompletion (de
huidige bron van waarheid), en de dode stubs verwijderd uit db.js.

Closes #9

 Evaluate the provided topics and relations and emit the actions to take via the emit_graph_actions tool.
 
-PROTECTED TOPICS — NEVER include these in merges (as deleteId) or in deletions:
-  • Topics with learning_relevance="exclude" are REFERENCE MATERIAL, kept on purpose
-    so R42 can still answer questions about them. They are intentionally outside
-    the theme-learning flow. Do not propose deleting or merging them away.
-  • Topics with relevance_locked=true are admin-pinned. Do not change their
-    learning_relevance and do not delete or merge them.
-These topics may appear as the keepId in a merge (others fold into them), and
-may appear as source/target of newRelations, but their own row must survive.
-
 Rules:
 1. Identify topics that mean exactly the same thing. Choose one to keep, one to delete (merges).
 2. Identify topics that are too vague, irrelevant, or malformed (deletions).
 3. Identify missing logical relations (depends_on, part_of, related_to, executed_by) between conceptually linked topics (newRelations).
 4. Evaluate learning_relevance. Mark purely operational topics (printer guides, etc.) as "exclude"; low-priority as "peripheral" (relevanceUpdates).
-   Skip topics where relevance_locked=true — omit them from relevanceUpdates entirely.
 
 Do not return the entire graph — only the actions to take.`,
