Adds the section "Using it from a DDD / hexagonal application" to docs/USAGE.md: which layer the bundle belongs to in a DDD / hexagonal host, how to keep the domain free of it, which ports, events and DTOs to build an adapter on (with a short sketch where it helps), and the known limitations.

Also adds the table-of-contents entry and a CHANGELOG [Unreleased] line.

Docs only; no code or behaviour change.

Summary by CodeRabbit

Walkthrough

The USAGE guide adds a section on using the bundle in a DDD or hexagonal application. The Unreleased changelog records the documentation update.

Changes: DDD usage guidance

Layer / File(s) Summary
Document DDD integration
docs/USAGE.md, docs/CHANGELOG.md
The guide describes the bundle’s presentation-only scope, password field binding and hashing guidance, Symfony PasswordType integration, configuration options, and a limitation. The table of contents links to the section, and the changelog records the addition.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Change: Other

Merge Risk: Low · previous review 07067

The change is mergeable with bounded documentation corrections: clarify theme registration and repeated-field options, and align the release note with the guide. Otherwise, readers may miss toggle controls or encounter an option error when following the guidance.

remove the unsupported claims about event integration and building an
anti-corruption layer.

Review comments at @docs/USAGE.md:
- Around line 236-237: Update the `extend_core_password_type` documentation to
distinguish opt-out syntax: describe `'toggle' => false` for a `PasswordType`
and `'options' => ['toggle' => false]` for both children of a `RepeatedType`.
Preserve the existing explanation of which password fields receive the toggle.
- Around line 235-237: Update the `use_toggle_form_theme` documentation to state
that when it is `false`, an active form theme must provide the toggle block;
otherwise password fields will have no toggle controls. Link to the existing
manual form-theme registration instructions.

Align the release note with the guide.

The guide describes a DTO and a port, but it does not explain event integration or an anti-corruption layer. Remove those claims from the release note.

- To keep even the form classes free of the bundle, use Symfony's own `PasswordType` and set
`extend_core_password_type: true`: every `PasswordType` (including `RepeatedType` of passwords and forms from other
bundles) gets the toggle, and opting out is `'toggle' => false`.

Document the form-theme prerequisite.

If use_toggle_form_theme is false and no active theme provides the toggle block, enabling the extension leaves password fields without toggle controls. Link to the manual form-theme registration instructions here.

Document the repeated-field opt-out syntax.

For a RepeatedType, adding 'toggle' => false directly can cause an undefined-option error. Pass it to both password children through 'options' => ['toggle' => false] instead.

Suggested fix

-  bundles) gets the toggle, and opting out is `'toggle' => false`.
+  bundles) gets the toggle. Opt out a `PasswordType` with `'toggle' => false`.
+  For a `RepeatedType`, use `'options' => ['toggle' => false]` for both children.
