feat: time-aware model routing for cron jobs (#317)

Route cron jobs to different models based on time of day.

- Peak hours (user active): cheaper model, user catches errors
- Off-peak hours (user absent): stronger model, errors go uncorrected

Config under smart_model_routing.cron_time_routing:
  enabled, timezone, peak_hours (start/end), peak_model, offpeak_model

Integrates into cron/scheduler.py via resolve_cron_turn_route(), which
checks time-aware routing first, then falls back to normal smart routing.

12 tests added (test_cron_time_routing.py). All 18 routing tests pass.

Closes #317

-# Honcho Memory Integration Evaluation (#322)
-
-## Source
-plastic-labs/hermes-honcho — full Honcho AI-native memory integration
-
-## Status: ALREADY IMPLEMENTED
-
-The Honcho integration has been fully ported to the main hermes-agent repository.
-
-## Components Found
-
-### 1. Client Configuration (`plugins/memory/honcho/client.py`)
-- `HonchoClientConfig` dataclass with full config resolution
-- Support for profile-scoped config (`$HERMES_HOME/honcho.json`)
-- Global config fallback (`~/.honcho/config.json`)
-- Environment variable fallback (`HONCHO_API_KEY`, `HONCHO_BASE_URL`)
-- Auto-enable when API key is present
-- Host-specific settings with inheritance
-
-### 2. Session Management (`plugins/memory/honcho/session.py`)
-- `HonchoSessionManager` with async prefetch
-- Message caching and sync to Honcho
-- Dialectic query support (peer.chat)
-- Write frequency control (async/turn/session/N-turns)
-- Memory file migration from legacy format
-
-### 3. MemoryProvider Interface (`plugins/memory/honcho/__init__.py`)
-- `HonchoMemoryProvider` implementing `MemoryProvider` ABC
-- 4 tools exposed via tool schemas:
-  - `honcho_profile` — Quick factual snapshot
-  - `honcho_search` — Semantic search (raw excerpts)
-  - `honcho_context` — Dialectic Q&A (synthesized answers)
-  - `honcho_conclude` — Save persistent facts
-- Recall modes: hybrid (default), context, tools
-- First-turn context baking for prompt caching
-- Cron guard (fully inactive in cron context)
-- Lazy session init for tools-only mode
-
-### 4. CLI Integration (`plugins/memory/honcho/cli.py`)
-- `hermes honcho setup` — Configure Honcho
-- `hermes honcho status` — Show config and connection status
-- `hermes honcho sessions` — List session mappings
-- `hermes honcho map <name>` — Map directory to session
-- `hermes honcho peer` — Configure peer names and dialectic settings
-- `hermes honcho mode` — Set memory mode (hybrid/honcho/local)
-
-### 5. Tests
-- `tests/test_honcho_client_config.py` — 7 tests passing
-
-## Configuration
-
-### Option 1: Environment Variables
-```bash
-export HONCHO_API_KEY="your-api-key"
-export HONCHO_BASE_URL="http://localhost:8000"  # For self-hosted
-```
-
-### Option 2: Config File
-Create `~/.hermes/honcho.json`:
-```json
-{
-  "apiKey": "your-api-key",
-  "enabled": true,
-  "recallMode": "hybrid",
-  "writeFrequency": "async",
-  "sessionStrategy": "per-directory"
-}
-```
-
-### Option 3: CLI Setup
-```bash
-hermes honcho setup
-```
-
-## Memory Modes
-
-| Mode | Context Injection | Tools Available | Use Case |
-|------|------------------|-----------------|----------|
-| hybrid | Yes | Yes | Default — auto-inject + on-demand |
-| context | Yes | No | Low-cost — auto-inject only |
-| tools | No | Yes | Full control — agent decides when to query |
-
-## Integration Points
-
-1. **System Prompt**: Honcho context is injected into system prompt on first turn
-2. **Tool Registry**: 4 tools available when recall_mode != "context"
-3. **Session End**: Messages flushed to Honcho on session end
-4. **Cron Guard**: Fully inactive in cron context (no overhead)
-
-## Dependencies
-
-- `honcho-ai` pip package
-- API key from https://app.honcho.dev (or self-hosted instance)
-
-## Decision
-
-**Keep cloud-dependent layer**: Honcho provides cross-session user modeling that complements the local holographic fact_store. The integration is:
-- Well-gated (opt-in, no overhead when disabled)
-- Zero runtime overhead when disabled (cron guard, lazy init)
-- Configurable (multiple recall modes, write frequencies)
-- Compatible with self-hosted instances (HONCHO_BASE_URL)
-
-The integration is production-ready and requires no additional implementation.
