#3 feat: add extra_context_type label (chat/document/notes) for input-aware extraction

[Anonymous]

Originally created by: TheoV823

Summary

• New extra_context_type column on users — nullable TEXT CHECK (IN 'chat', 'document', 'notes'); migration in migrate_add_extra_context_type.sql
• Type-aware extraction prompt — _CONTEXT_TYPE_HINTS dict appends a focus hint to the Claude system prompt based on input type: chat → conversation patterns, document → formal structure, notes → heuristics and rules of thumb
• flask add-user --extra-context-type — optional chat|document|notes flag; raises UsageError if provided without --extra-context-path

Test Plan

• [x] 86/86 tests passing
• [x] python -m pytest tests/ -q to verify
• [x] flask add-user --help shows --extra-context-type [chat|document|notes]
• [x] Guard tested: --extra-context-type without --extra-context-path exits non-zero

Note

This branch is based on feature/signal-profile-refactor (PR [#1]). Merge order: PR [#1] → PR [#2] → this PR.
