Update Configuration Schema for Parallel Execution

[hawkeyexl]

Description

Add concurrentRunners property to the configuration schema to support parallel test execution.

Requirements

Schema Changes

Update the configuration schema (config_v3.schema.json) to include:

{
  "concurrentRunners": {
    "type": ["integer", "boolean"],
    "default": 1,
    "minimum": 1,
    "description": "Number of concurrent test runners. Set to true to use CPU core count (capped at 4)."
  }
}

Validation Rules

• Accept integer values ≥ 1
• Accept boolean true value
• Reject boolean false (invalid configuration)
• Default to 1 when not specified

Files to Modify

• src/schemas/src_schemas/config_v3.schema.json
• Update any related TypeScript definitions if they exist
• Update schema validation tests

Acceptance Criteria

• Schema accepts "concurrentRunners": 1
• Schema accepts "concurrentRunners": true
• Schema accepts "concurrentRunners": 8 (any integer ≥ 1)
• Schema rejects "concurrentRunners": 0
• Schema rejects "concurrentRunners": -1
• Schema rejects "concurrentRunners": false
• Schema rejects "concurrentRunners": "invalid"
• Default value is 1 when property omitted
• Validation tests pass

Implementation Notes

• Follow existing schema patterns in the codebase
• Ensure the description clearly explains the boolean true behavior
• Add appropriate examples to the schema if the pattern supports it
