Support array shape return documentation

[Levdbas]

Adds support for PHPDoc array-shape return types such as array{address?: string, lat?: string}|false in generated reference docs.

What changed:

• Extracted shared array definition rendering so return tags can reuse the same nested field-list formatting as array @param descriptions.
• Rendered array-shape return types as a concise union type, for example array|false, while expanding the shape fields in the detailed return documentation.
• Normalized method overview tables so array shapes do not produce unwieldy inline return types.
• Added coverage for a business location return shape including location_link and route_link.

Generated Markdown

For the business location return shape, Teak now generates:

**Returns:** `array|false` The business location, or false when none is configured.

<ul>
<li>**address**<br>`string`</li>
<li>**lat**<br>`string`</li>
<li>**lng**<br>`string`</li>
<li>**zoom**<br>`int`</li>
<li>**place_id**<br>`string`</li>
<li>**name**<br>`string`</li>
<li>**street_number**<br>`string`</li>
<li>**street_name**<br>`string`</li>
<li>**street_name_short**<br>`string`</li>
<li>**city**<br>`string`</li>
<li>**state**<br>`string`</li>
<li>**state_short**<br>`string`</li>
<li>**post_code**<br>`string`</li>
<li>**country**<br>`string`</li>
<li>**country_short**<br>`string`</li>
<li>**location_link**<br>`string`</li>
<li>**route_link**<br>`string`</li>
</ul>

The methods overview shows the same return type concisely as `array` or `false`.

Validation:

• vendor/bin/phpunit passes all assertions. PHPUnit still reports the existing risky ClassCompilerTest::testDefault because it has no assertions.
