Validation schema/scope is too narrow and will generate misleading warnings.
Line 333’s allowlist misses several valid agent keys already consumed in this file (e.g., tasks, allow_delegation, planning, approval, streaming, etc.), and Line 336 only validates agents (not canonical roles). This will produce false warnings and miss typos for roles-only configs.
Consider validating against a complete supported key set and covering canonical roles configs (without double-reporting when both sections exist).

agents-format YAMLs
_validate_agents_config is called after the canonical conversion (lines 532–547) that copies every entry from config['agents'] into the freshly created config['roles']. At that point the config dict contains both an agents key and a roles key with identical entries. The validator iterates over both sections, so every typo fires twice — once as Unknown field '...' in agent 'X' and again as Unknown field '...' in role 'X'. Move the validation call to before the canonical conversion (before line 532), or skip whichever of the two sections was synthetically created. The unit tests call _validate_agents_config directly on the raw YAML (before conversion), so they never exercise this code path and will not catch the duplication.
Fixes #1628
This PR implements validation for agents.yaml field names with fuzzy matching suggestions to help users catch typos.
Problem
agents.yaml parsing currently ignores typos in field names silently, causing agents to run with empty default values instead of intended configuration.
Solution
Example
Before: Silent failure with instructions = empty
After: WARNING: Unknown field 'instrutions' in agent 'researcher'. Did you mean 'instructions'?
