chore(schema): strict oneOf branches and DRY env_directive in schemas

[jdx]

Summary

• Tighten JSON schema validation and reduce duplication. Schema-only changes.

Changes

• In schema/mise.json: annotate oneOf branches for env_directive with explicit required properties.
• In schema/mise-task.json:
  • Same strict oneOf annotations for env_directive.
  • DRY env._.path object forms by referencing #/$defs/env_directive (both direct object and array-item object variants).

Why

• Ensures strictRequired validation passes during lint.
• Centralizes repeated shapes for easier maintenance.

Impact

• No runtime behavior changes; documentation and tooling validation only.

Pull Request Overview

This PR tightens JSON schema validation and reduces duplication by adding strict oneOf branch validation and implementing DRY principles for env_directive definitions.

• Adds explicit type and properties declarations to oneOf branches in env_directive schemas for stricter validation
• Replaces duplicated env_directive object definitions with $ref references to the centralized definition
• Ensures all oneOf branches have complete type and property specifications for better schema compliance

The path property definition is duplicated here from the parent properties section (lines 10-21). This creates maintenance overhead since changes to the path schema need to be updated in multiple places.
