Major refactoring of the team system with multiple improvements:
## Removed legacy delegation tools
- Delete `delegate.go`, `delegate_async.go`, `delegate_sync.go`, `delegate_events.go`,
`delegate_policy.go`, `delegate_prep.go`, `delegate_state.go`, `delegate_search_tool.go`
- Delete `evaluate_loop_tool.go`, `handoff_tool.go`
- Remove all references and registrations from tool manager and policy
- Clean up TEAM_PLAYBOOK_IDEAS.md and TEAM_SYSTEM.md (moved to docs)
## Rename await_reply → ask_user
- Rename action `await_reply` → `ask_user`, `clear_followup` → `clear_ask_user`
- Rename functions `executeAwaitReply` → `executeAskUser`, `executeClearFollowup` → `executeClearAskUser`
- Update system prompt with stronger wording to prevent model misuse
- Model was confusing "await_reply" with general waiting; "ask_user" is unambiguous
## Fix auto-followup false positives
- Add `HasActiveMemberTasks(ctx, teamID, excludeAgentID)` store method
- Guard `autoSetFollowup()` in consumer: skip when lead has active member tasks
- Prevents auto-followup when lead is orchestrating teammates (not waiting for user)
## Task identifier zero-padding
- Change format from `T-1-xxxx` → `T-001-xxxx` (3-digit minimum)
## Refactor workspace WS handlers to filesystem-only
- Rewrite `teams.workspace.list/read/delete` to use pure filesystem (os.ReadDir/ReadFile/Remove)
- Remove DB dependency from workspace WS handlers
- Consistent with storage handler and workspace tools
- Simplify TeamWorkspaceFile type and frontend hook
## Add team events listing API
- New WS method `teams.events.list` with team_id, limit, offset params
- New HTTP endpoint `GET /v1/teams/{id}/events` with bearer auth
- New `ListTeamEvents(ctx, teamID, limit, offset)` store method
- JOIN with team_tasks for team-wide event filtering
## Extract team access policy
- New `team_access_policy.go` — centralized team tool access control
## Migration 000019: team_id columns
- Add team_id foreign key columns to relevant tables
## Other improvements
- Add team_id propagation through agent loop, tracing, sessions
- Update i18n locale files (en/vi/zh) for new tool labels
- Update frontend builtin-tools page and require-setup component
- Bump RequiredSchemaVersion for migration 000019
Add independent `share_memory` config flag to control memory and
knowledge graph sharing separately from workspace folder isolation.
- Add ShareMemory field to WorkspaceSharingConfig
- Decouple WithSharedMemory(ctx) from shouldShareWorkspace() in loop.go
- Add shouldShareMemory() helper independent of workspace sharing
- Fix KG Traverse CTE to scope user_id in recursive step (pre-existing bug)
- Add memory toggle UI with violet styling in workspace sharing section
- Add i18n translations (en/vi/zh) for new memory sharing controls
- Add unit tests for shouldShareMemory() independence
Add workspace_sharing config in other_config JSONB to control per-user
workspace isolation. When enabled, users share the base workspace directory
instead of isolated subfolders — configurable separately for DMs and groups,
with a per-user allowlist override.
Backend: WorkspaceSharingConfig struct, ParseWorkspaceSharing(), conditional
isolation in loop.go/loop_history.go, 7 unit tests.
Frontend: prominent always-visible config section with contact search
combobox, sticky save bar layout fix, i18n (en/vi/zh).
- Add tool status display on channels during tool execution (streaming preview + reactions)
- Emit agent.activity events at phase transitions (thinking, tool_exec, compacting)
- Enrich delegation progress with per-member activity and tool info
- Add LLM-based intent classifier for DM status queries when agent is busy
- Keyword fast-path for cancel/status patterns (no LLM cost)
- Falls back to LLM classification with 5s timeout
- Supports status_query (immediate reply) and cancel (abort run) intents
- Register/unregister runs in makeSchedulerRunFunc for channel inbound tracking
- Add sessionRuns secondary index in Router for O(1) IsSessionBusy lookups
- Add intent_classify config toggle (global default + per-agent override)
- Add tool_status config toggle for channel tool status display
- Add i18n keys and translations (en/vi/zh) for status messages
- Add web UI config toggles for intent_classify and tool_status
