The $AGENT_HOME environment variable was referenced by skills (e.g.
para-memory-files) but never actually set, causing runtime errors like
"/HEARTBEAT.md: No such file or directory" when agents tried to resolve
paths relative to their home directory.
Add agentHome to the paperclipWorkspace context in the heartbeat service
and propagate it as the AGENT_HOME env var in all local adapters.

Major improvements to the Pi local adapter:
Bug Fixes (Greptile-identified):
- Fix string interpolation in models.ts error message (was showing literal ${detail})
- Fix tool matching in parse.ts to use toolCallId instead of toolName for correct
multi-call handling and result assignment
- Fix dead code in execute.ts by tracking instructionsReadFailed flag
Feature Improvements:
- Switch from print mode (-p) to RPC mode (--mode rpc) to prevent agent from
exiting prematurely and ensure proper lifecycle completion
- Add stdin command sending via JSON-RPC format for prompt delivery
- Add line buffering in execute.ts to handle partial JSON chunks correctly
- Filter RPC protocol messages (response, extension_ui_request, etc.) from transcript
Cost Tracking:
- Extract cost and usage data from turn_end assistant messages
- Support both Pi format (input/output/cacheRead/cost.total) and generic format
- Add tests for cost extraction and accumulation across multiple turns
All tests pass (12/12), typecheck clean, server builds successfully.
