chore(config): bump version to 4.0.0-SNAPSHOT

[bpamiri]

Summary

Bumps the framework version from 3.1.0 to 4.0.0-SNAPSHOT across all version declarations.

Rationale

The scope of changes on develop since the 3.0 release warrants a major version bump:

• LuCLI replaces CommandBox as the CLI engine (breaking change for existing CLI workflows)
• SQLite as primary platform — zero-config out of box
• Rebrand from CFWheels to Wheels (namespace/branding changes)
• In-process CLI architecture — commands run in same JVM context
• New scaffold system — wheels new with LuCLI templates
• Security hardening — 7 vulnerability fixes across model/view/controller/middleware layers
• Package system — replacing legacy plugins/ with packages/vendor/

Files changed

Test plan

• CI passes (version string doesn't affect test execution)
• application.wheels.version reports 4.0.0-SNAPSHOT at runtime
