Release v0.10.0

What's Changed

Added

• Attachment file storage: HEAD/GET/POST /knowledge/entries/{id}/file for checking, downloading, and uploading original attachment files (e.g., PDFs stored alongside their extracted text)
• KnowledgeFileService: filesystem-backed store for original attachments with configurable size limit
• Multi-collection routing via X-Knowledge-Collection header: the KB SPA uses knowledge_entries (default), AgentForge Notes uses kb_note_entries
• knowledge_registry module: collection-scoped service caching, FastAPI dependency injection, and ensure_all_collections() startup hook
• force_unique flag on CreateEntryRequest. Bypasses content-hash dedup so the same text can be stored under multiple parents
• Auto-relink: creating a duplicate entry with a parent_id reattaches the existing entry under the new parent instead of returning 409
• metadata field on UpdateEntryRequest (was already on create and now on updatable)
• Config keys: knowledge.notes_collection_name, knowledge.files_dir, knowledge.max_attachment_bytes
• @kb and @notes custom agent examples in custom_agents.example.yaml
• markdown/custom-agents/notes.md system prompt for the Notes agent
• Notes-aware WebSocket session routing: source=notes sessions auto-scope kb_search to the notes collection
• extracted_bytes in /knowledge/extract response metadata
• pdftotext page-marker formatting (--- Page N ---) and scaled timeouts for large PDFs

Changed

• Knowledge API routes use FastAPI Depends() injection instead of a module-level singleton. Each request resolves the correct collection-scoped service
• KnowledgeVectorService accepts an optional collection_name parameter (defaults to settings.knowledge.collection_name)
• PDF extraction prefers pdftotext for large files (>5 MiB) and pdfplumber for smaller ones (was pdfplumber-first with pdftotext fallback)
• delete_entry also removes stored attachment files for the entry (*optionally)
