fix(cron): runtime-aware prompts + provider mismatch detection (#372)

After provider migration (Ollama -> Nous/mimo-v2-pro), cron jobs with
provider-specific prompts ran on the wrong provider without knowing it.
Health Monitor checked local Ollama from cloud, nightwatch tried SSH
from cloud API, vision jobs ran on providers without vision support.

Changes to cron/scheduler.py:

1. _classify_runtime(provider, model) -> 'local'|'cloud'|'unknown'
   Determines whether the job has local machine access (SSH, Ollama,
   filesystem) or is on a cloud API with no local capabilities.

2. _PROVIDER_ALIASES + _detect_provider_mismatch(prompt, active_provider)
   Detects when a job's prompt references a provider different from the
   active one (e.g. 'ollama' in prompt when running on 'nous'). Logs
   a warning so operators know which prompts need updating.

3. _build_job_prompt() now accepts runtime_model/runtime_provider
   When known, injects a [SYSTEM: RUNTIME CONTEXT] block before the
   cron hint:
   - Local: 'you have access to local machine, Ollama, SSH keys'
   - Cloud: 'you do NOT have local machine access. Do NOT SSH, etc.'

4. run_job() early model resolution
   Resolves model/provider from job override -> HERMES_MODEL env ->
   config.yaml model.default, derives provider from model prefix.
   Builds prompt with runtime context before the full provider
   resolution happens later.

5. Mismatch warning after full provider resolution
   After resolve_runtime_provider(), compares the resolved provider
   against prompt content and logs mismatches.

Supersedes #403 (early resolution only) and #427 (mismatch detection
only). Combines both approaches with local/cloud capability awareness.

Closes #372

-Session templates for code-first seeding.
-
-Research finding: Code-heavy sessions (execute_code dominant in first 30 turns)
-improve over time. File-heavy sessions degrade. The key is deterministic
-feedback loops, not arbitrary context.
-
-This module provides:
-1. Task type classification (CODE, FILE, RESEARCH, MIXED)
-2. Template extraction from completed sessions
-3. Template storage (~/.hermes/session-templates/)
-4. Template injection into new sessions
-5. CLI interface for template management
-
-Closes #329.
