feat: #3610329 Back to DEV

Back to DEV after the Varbase Project 11.0.3 release.

Changes

• composer.json: version 11.0.3 -> 11.0.x-dev; vardot/varbase and vardot/varbase-patches ~11.0.0 -> 11.0.x-dev.
• Remove composer.lock and patches.lock.json (kept only on release tags; the DEV branch keeps yarn.lock).
• README.md version badge stays at the latest release (11.0.3).

Follows the release of varbase_project 11.0.3. Plan: #3610329.

AI-Generated: Yes (Used Claude Code to revert composer.json to 11.0.x-dev and drop the lock files)
