linonetwo 0312a49925 feat: Implement background task management for agent instances 
- Added functionality to restore heartbeat timers and alarms for active agents upon service initialization.
- Introduced methods to retrieve active background tasks and cancel them via the UI.
- Enhanced alarm clock tool to persist alarm data in the database, ensuring alarms survive app restarts.
- Updated agent instance schema to include scheduled alarm data.
- Modified prompt concatenation logic to support context window size for message history.
- Removed system prompt parameter from model parameters schema and related components.

Agent Enhancement — Session 2026-03-05

Changes Made

1. Agent Switcher moved to header with AutoComplete search

  • Moved AgentSwitcher from InputContainer (bottom left) to ChatHeader (top bar, next to title)
  • Dropdown now opens downward instead of upward
  • Added MUI Autocomplete with inline search box — filters agents by name and description
  • Cleaned up unused props from InputContainer and ChatTabContent

2. Tool Approval wired into execution flow

  • evaluateApproval() + requestApproval() now called before every executeToolCall() in defineTool.ts
  • Also integrated into executeAllMatchingToolCalls() for batch approval
  • Denied tools return an error tool result and yield back to the agent
  • Pending tools block execution until the user responds via resolveApproval()

3. Context window token truncation

  • Added contextWindowSize optional field to FullReplacementParameterSchema
  • After filterMessagesByDuration(), messages are now trimmed by token count
  • Oldest messages are removed first; 70% of context budget allocated to history
  • Default set to 120,000 tokens in both Task Agent and Plan Agent configs

4. Heartbeat auto-wake configuration

  • New AgentHeartbeatConfig interface on AgentDefinition (enabled, intervalSeconds, message, activeHoursStart/End)
  • heartbeatManager.ts manages per-agent setInterval timers
  • Heartbeats started after successful framework run, stopped on close/cancel/delete
  • Active hours filtering supports overnight ranges (e.g. 22:00-06:00)
  • Persisted via heartbeat column on AgentDefinitionEntity

5. Alarm clock recurring support

  • alarm-clock tool now accepts optional repeatIntervalMinutes parameter
  • First fire happens at the specified wakeAtISO, then repeats at the interval
  • cancelAlarm() clears both setTimeout and setInterval timers

6. Tool result smart truncation

  • addToolResult() now truncates results exceeding 32,000 characters
  • Truncated results include a [... truncated] marker with original length
  • Prevents a single wiki-search result from consuming the entire context window

7. Step definition fix for embedding-only mock rules

  • agent.ts step definition now accepts mock rules with only embedding (no response)
  • Previously if (response) rules.push(...) would skip embedding-only rules
