5eef3fed1a feat: warm session provisioning — pre-proficient agent sessions (#327)
Some checks failed
Forge CI / smoke-and-build (pull_request) Failing after 1m10s
Marathon sessions (100+ msgs) have lower per-tool error rates than
mid-length sessions. This implements warm session provisioning to
pre-seed new sessions with successful tool-call patterns.

agent/warm_session.py:
  - WarmSessionTemplate dataclass with ToolCallExample entries
  - extract_successful_patterns() mines SessionDB for marathon sessions
  - build_warm_conversation() converts templates into conversation_history
  - save/load/list templates persisted to ~/.hermes/warm_sessions/

tools/warm_session_tool.py:
  - warm_session tool with build/list/load/delete actions
  - Registered in the skills toolset

Usage:
  Agent calls warm_session(action='build', name='general') to mine patterns
  from existing marathon sessions. Then new sessions can start with the
  warm conversation_history injected via run_conversation().

Integration:
  No changes to run_agent.py needed — the existing conversation_history
  parameter already handles this. The warm tool builds the history,
  caller injects it.

21 tests added, all passing.

Closes #327

"""Warm Session Provisioning — pre-proficient agent sessions.
Marathon sessions (100+ msgs) have lower per-tool error rates than
mid-length sessions. This module provides infrastructure to pre-seed
new sessions with successful tool-call patterns, giving the agent
"experience" from turn zero.
Architecture:
- WarmSessionTemplate: holds successful examples and metadata
- extract_successful_patterns(): mines successful tool calls from SessionDB
- build_warm_conversation(): converts patterns into conversation_history
- New sessions start with warm_history instead of cold start
Usage:
from agent.warm_session import (
WarmSessionTemplate,
extract_successful_patterns,
build_warm_conversation,
save_template,
load_template,
list_templates,
