Release v0.9.0

What's Changed

Changed

• RAG @ aliases centralized in agentforge/mode_prefixes.py (shared by mode_routing and intent_classifier).
• Botty engine reads analysis_interval, max_frequency_seconds, and dismissal_cooldown_seconds from config.
• canvas.enabled and botty.enabled in config.yaml now gate Canvas init and the /ws/botty route (defaults remain true).
• prompt_lab.enabled gates Prompt Lab DB init and /api/prompt-lab/* endpoints; canvas.enabled also gates the /api/canvas/* router (not just init).
• Chat sessions are namespaced by chat_sessions.source (web, kb, …): clients pass overrides.source and/or ?source= on /ws/chat; worker auto-create reads the active job's overrides. Agent Chat lists source=web only.
• web/server/api.py imports hoisted to module top; sql_schema_tool stays lazy (private/gitignored module).
• In-code RAG comments in ws_endpoint.py now treat @qdrant as canonical (@docs / @find as aliases).
• OllamaSettings profile resolution always delegates to agentforge.config.ConfigManager (removed duplicate _merge_profile_chain fallback).
• Config loading consolidated: app/config.py and agentforge.config.ConfigManager both use load_merged_yaml() (framework-config + config.yaml + split profiles). ConfigManager.raw exposes the merged dict. When gitignored config files are absent, load_merged_yaml() falls back to the committed *.example.yaml templates (CI / fresh clone).
• Legacy per-product Google connector plugins (gmail, google_drive, bigquery, youtube) removed; unified google connector only. Unmigrated SQLite rows are skipped at startup (see scripts/list-legacy-connections.py).
• Knowledge Database content types are now note, reference, documentation, document, cheatsheet, and snippet (replacing the earlier code / command / url / config / error_solution / api_example set). Update clients and any indexed entries accordingly.
• custom_agents.yaml is gitignored (per-deployment, like config.yaml); shipped template is custom_agents.example.yaml with example fallback in the loader.
• RAG search mode: @qdrant is canonical; @docs and @find are documented aliases (all three route to the same mode and can appear anywhere in a prompt).
• Mode prefix detection extracted from ws_endpoint.py to web/server/mode_routing.py.
• Put.io / Premiumize (cloud_tools) moved from register_core_tools to register_optional_tools (still registered by register_all_tools when credentials are set).

Added

• GET /knowledge/list: slim metadata listing for the browse view (no content body; optional limit, default 2000).
• custom_agents.example.yaml template for custom agents (copy to gitignored custom_agents.yaml).
• scripts/list-legacy-connections.py: read-only audit of legacy per-product Google connector rows.
• tests/test_mode_routing.py: prefix stripping for @qdrant / @docs / @find.
• tests/test_config_loader.py: merged YAML parity between app.config and agentforge.config.
• tests/test_feature_flags.py: default canvas.enabled / botty.enabled settings.
• tests/test_mode_prefixes.py, tests/test_botty_engine.py: shared RAG aliases and Botty rate limits.
• web/server/session_source.py, tests/test_session_source.py: shared session source resolution for WS and worker paths.

Removed

• get_connector_config() (unused after unified Google OAuth cleanup).
• strip_agent_prefix() (unused after mode-routing extraction).
• translate_legacy_locality() (empty map; inlined at call sites).
• tools.shell.sudo_password startup warning in the CLI (the key was already ignored; interactive sudo is the only path).
• AGENTFORGE_WORKER_LOCALITY env fallback in worker role resolution (use AGENTFORGE_WORKER_ROLE).
• Legacy connectors.google.gmail.credentials_dir config path for OAuth client secrets (use connectors.credentials_dir or GMAIL_CREDENTIALS_DIR).

Breaking

• Knowledge Database content type rename (see Changed above).
• Legacy per-product Google connector plugins removed (see Changed above).
• Chat session listing is scoped by source; clients must pass overrides.source / ?source= where appropriate.
