feat: warm session provisioning — pre-proficient agent sessions (#327)

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,
