Adds a bundled backend plugin (plugins/backsearch/) with two check_fn-gated
tools, backsearch and backfetch, backed by BackSearch from General Reasoning
(https://search.openreward.ai). Every request carries an as_of date; search
returns only documents crawled on or before it, and fetch returns the article
text as archived at that time — forecasting backtests, quant research loops,
RL environments, and reproducible benchmarks.
- plugins/backsearch/: plugin.yaml (kind: backend, auto-loads), tools.py
(handlers, schemas, 402/401/404 typed errors, as_of validation, fetch
text cap), __init__.py (registers into the 'backsearch' toolset)
- toolsets.py: backsearch toolset entry
- hermes_cli/tools_config.py: hermes tools row + TOOL_CATEGORIES setup flow,
default-off with OPENREWARD_API_KEY auto-enable (mirrors x_search/HASS)
- hermes_cli/config.py: OPENREWARD_API_KEY in OPTIONAL_ENV_VARS
- docs: tools-reference, toolsets-reference, built-in-plugins
- tests/plugins/test_backsearch_plugin.py: 32 tests, real imports, httpx
