fix(agent-chat): streaming state leak, document parser magic bytes, HITL flow
### Bugfixes — Agent Chat 'Думаю' State Leak
- fix(agent-chat): loadHistory() now resets streamingState/idle + cancels stale
submission — prevents 'Думаю' state leak across conversation switches
- fix(agent-chat): onDisconnected/onDisconnectedPermanent cascade to
streamingState — prevents permanent hang on connection loss during stream
- fix(agent-chat): guard on isLoadingHistory — prevents false commit
of 'agent unavailable' fallback when switching conversations
- fix(agent-chat): remove race in _sendNow empty-response check vs Svelte
microtask (duplicate logic removed, handles correctly)
- fix(stream-processor): confirm_resolved now appends msg.text to partialText
instead of dropping it
### Bugfixes — Backend PDF Upload
- fix(document-parser): _detect_format_by_magic() — reads file header magic
bytes as fallback when Gradio loses filename
- fix(document-parser): improved name extraction — tries orig_name, path stem
- fix(document-parser): @RELATION AgentChatTypes -> AgentChat.Types
### HITL Flow & Agent Chat Improvements
- feat(agent): HITL resume confirm/deny with userId/userJwt/envId propagation
- feat(agent): confirm_required metadata fallback via aget_state() after
'Event loop is closed' error during interrupt
- feat(agent): interrupt_before re-enabled via AGENT_CONFIRM_TOOLS env var
- feat(frontend): debug panel with connection/stream state monitoring
- feat(frontend): AgentChatModel constructor options + onBeforeSend callback
- feat(frontend): crypto.randomUUID() for local conversation ID on first send
### Backend Agent Refactoring
- refactor(agent): langgraph_setup — monkey-patch for PydanticSerializationError
- refactor(agent): tools.py — dual identity headers, expanded tool set
- refactor(agent): run.py — _find_free_port, Gradio server port fallback
- refactor(agent): app.py — file size validation, message truncation, HITL path
### Frontend
- feat(dashboard-hub): DashboardHubModel with filters, pagination, git actions
- feat(ui): DateRangeFilter component
- feat(i18n): new dashboard keys; cache tooltips fix
- fix(i18n): full run tooltips — cache is NOT ignored
### Semantic Protocol
- chore(agents): update all agents with canonical format
