…3.1 (#2206) Re-apply upstream heartbeat protocol improvements that were lost during PR #2191 wholesale restoration of heartbeat-runner.ts. Changes re-applied: - ackMaxChars configuration — configurable max chars for heartbeat ack responses, preventing verbose acks from flooding channels - HEARTBEAT.md file gating — skip heartbeat when file is effectively empty, with bypass for exec/cron/wake events and ENOENT handling - HEARTBEAT_TOKEN structured protocol — heartbeat OK uses structured token instead of raw text, paired with stripHeartbeatToken extraction - buildOutboundSessionContext — session-aware outbound delivery for heartbeat-originated messages - Exec fallback text — better exec-completion handling when token stripping empties the response - HeartbeatSkipReason type — typed skip reasons for heartbeat skip reporting - stripLeadingHeartbeatResponsePrefix — regex boundary fix preventing short prefixes like "Hi" from stripping words like "History" Intentionally NOT re-applied (gutted subsystem code): - bootstrapContextMode / lightContext (Pi bootstrap) - includeReasoning / resolveHeartbeatReasoningPayloads (Pi reasoning) - resolveHeartbeatPrompt signature change (deferred to #2194) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
