Replace sovereignty-stamp validation in supercommit_max.sh with clean Git automation

[Copilot]

supercommit_max.sh required hardcoded sovereignty stamps (@CertezaAbsoluta, @lo+erestu, PCT/EP2025/067317, etc.) in every commit message, making the script unusable for standard Git workflows.

Changes

• Removed stamp validation logic and the long default sovereignty message
• Added colored output ([START], [OK], [SUCCESS], [SKIP], [ERROR], [FINISH])
• Added .git directory existence check before any Git operations
• Changed default commit message to "Update: $(date +'%Y-%m-%d %H:%M:%S')" — still overridable via $1
• Changed push from git push (upstream-dependent) to explicit git push origin "$CURRENT_BRANCH"
• Changed git add -A → git add . per spec

# Default message when no argument provided
MESSAGE=${1:-"Update: $(date +'%Y-%m-%d %H:%M:%S')"}

# Push to current branch explicitly
CURRENT_BRANCH=$(git rev-parse --abbrev-ref HEAD)
git push origin "$CURRENT_BRANCH"

Wrapper scripts (percommit_max.sh, TRYONYOU_SUPERCOMMIT_MAX.sh) delegate via exec and require no changes.
