Description

PR #980 (ff351aad) renamed the security-planning collection to security. Subsequently, PR #979 (06f826ca) incorrectly re-created security-planning as a separate collection to house SSSC Planner artifacts, instead of adding those artifacts to the existing security collection.

This results in duplicate collection manifests and a security-planning extension in the marketplace that should not exist.

Expected Behavior

All security-related artifacts (Security Planner, SSSC Planner, RAI Planner, and their prompts/instructions) should be in the security collection. There should be no security-planning collection.

Required Changes

• Move all files from .github/{agents,prompts,instructions}/security-planning/ and .github/instructions/sssc-planning/ to .github/{agents,prompts,instructions}/security/
• Update all path references in collection YAMLs, agent files, and documentation
• Delete security-planning collection manifests and plugin outputs
• Remove security-planning entry from marketplace.json
• Regenerate plugins
