Support Psalm 7

[koriym]

Summary

• Switch vimeo/psalm to 7.x-dev@dev.
• Add the Psalm 7-required external mutation-free annotations for internal helper methods.

Why

be-framework/skeleton wants to consume Psalm 7 dev, but this plugin currently requires Psalm 6. This updates the plugin constraint and fixes the new Psalm 7 checks so downstream dependency resolution can move forward.

Verification

• composer validate --no-check-publish
• composer tests

Poem

🐰 A rabbit hops through Psalm's verdant fields,
Where v7 now blooms and true purity yields!
Annotations mark methods forever pure,
No mutations here—our analysis secure! ✨
