Condense AI template instructions and bump version to 1.0.96

[noelsaw1]

Motivation

• Reduce the instruction file size to improve AI agent context windows while preserving actionable guidance for template completion.
• Keep required guidance for metadata extraction, template generation, output formats, and running scans on external paths.
• Record the change with a version bump so release notes reflect the documentation update.

Description

• Replace dist/TEMPLATES/_AI_INSTRUCTIONS.md with a concise, 67-line instruction set that preserves required steps for reading user files, extracting NAME/VERSION, using the template filename as PROJECT_NAME, and handling failures.
• Update dist/bin/check-performance.sh header to # Version: 1.0.96 to reflect the documentation change.
• Add a 1.0.96 entry to CHANGELOG.md describing the condensed AI template instructions.

Testing

• No automated tests were run because this is a documentation-focused change.
• Files were reviewed locally to verify the condensed instructions contain the key required steps and the VERSION string was updated.
• No runtime behavior or scan logic was modified, so existing test fixtures and scripts remain unaffected.
