* cron: skip delivery for HEARTBEAT_OK responses
When an isolated cron job has deliver:true, skip message delivery if the
response is just HEARTBEAT_OK (or contains HEARTBEAT_OK at edges with
short remaining content <= 30 chars). This allows cron jobs to silently
ack when nothing to report but still deliver actual content when there
is something meaningful to say.
Media is still delivered even if text is HEARTBEAT_OK, since the
presence of media indicates there's something to share.
* fix(heartbeat): make ack padding configurable
* chore(deps): update to latest

* fix: ensure type:object in sanitized tool schemas for Antigravity API
The sanitizeSchemaForGoogle function strips unsupported JSON Schema
keywords like anyOf, but this can leave schemas with 'properties' and
'required' fields without a 'type' field. Both Google's Gemini API and
Anthropic via Antigravity require 'type: object' when these fields exist.
This fix adds a post-sanitization check that ensures type is set to
'object' when properties or required fields are present.
Fixes errors like:
- Gemini: 'parameters.properties: only allowed for OBJECT type'
- Anthropic: 'tools.6.custom.input_schema.type: Field required'
* fix: regenerate pi-ai patch with proper pnpm format
The patch now correctly applies via pnpm patch-commit, fixing:
- Thinking blocks: skip for Gemini, send with signature for Claude
- Schema sanitization: ensure type:object after removing anyOf
- Remove strict:null for LM Studio/Antigravity compatibility
Tested with all Antigravity models (Gemini and Claude).
* fix: strip thinking tags from block streaming output to prevent Gemini tag leakage
