v0.2.0
Opt-in ALTCHA with global + per-form settings
ALTCHA is now opt-in (off by default) with admin UI, instead of protecting every Gravity Form automatically.
- Global "Enable for all forms" toggle — Forms → Settings → ALTCHA.
- Per-form "Enable ALTCHA for this form" toggle — each form's Settings → ALTCHA tab.
A form is protected when the global toggle is on or that form's own toggle is on. The genero/gravityforms_altcha/should_protect filter still overrides the saved settings.
⚠️ Behavior change
Flips the default from opt-out to opt-in. After upgrading, no form is protected until a toggle is enabled. Sites relying on universal coverage should turn on "Enable for all forms" after updating.
