• Added dependency/package-script-drift for changed risky lifecycle scripts.
• Added package_scripts config for paths, lifecycle scripts, severity, and disabling the rule.
• Unavailable package manifest content is surfaced as analysis/content-unavailable instead of silently skipping lifecycle drift analysis.
• Package/report metadata is aligned to 0.2.4.

Not included:

• dependency additions
• lockfile mismatch
• CODEOWNERS / reviewer evidence
• maintainer override storage
• npm publishing
• Marketplace settings changes
