…w flow content (capricorn86#2058)

Fixes capricorn86#2052

## Problem

The caption element was incorrectly configured with contentModel: textOrComments,
which only allowed text nodes and comments. Per the HTML spec, caption elements
should contain flow content (inline and block elements), except table elements.

This caused elements like <b>, <em>, <span>, etc. to be incorrectly moved
outside the caption during parsing.

## Changes

### packages/happy-dom/src/config/HTMLElementConfig.ts

Updated caption element configuration to match the HTML spec and follow the
same pattern as td/th elements:

- Changed contentModel from textOrComments to noForbiddenFirstLevelDescendants
- Added forbiddenDescendants: table structure elements (table, tbody, thead,
  tfoot, tr, td, th, col, colgroup)
- Added permittedParents: ['table'] to ensure caption only appears in tables

### packages/happy-dom/test/html-parser/HTMLParser.malformedHTML.test.ts

Added comprehensive test coverage for caption element content model:
- Inline elements preservation (b, strong, em, span, a)
- Nested inline elements
- Block-level elements (p, div)
- Table element prohibition
- Content serialization
- permittedParents validation (wrong parent, standalone, correct parent)

## Implementation Details

This fix follows the same pattern as PR capricorn86#2007 for paragraph elements, using
the existing noForbiddenFirstLevelDescendants content model. While this
doesn't recursively check deeply nested table elements, it matches the
existing codebase patterns and handles the vast majority of real-world cases.

* fix: [#2035] Updates README.md for the server-renderer package (#2037)

* feat: [#241] Add canvas adapter pattern for pluggable rendering support

Adds ICanvasAdapter interface and static setCanvasAdapter() method to HTMLCanvasElement,
allowing users to plug in real canvas implementations like node-canvas.

Changes:
- Add ICanvasAdapter interface with getContext(), toDataURL(), toBlob() methods
- Add HTMLCanvasElement.setCanvasAdapter() and getCanvasAdapter() static methods
- Delegate canvas operations to adapter when set
- Add NodeCanvasAdapter implementation using node-canvas library
- Add comprehensive tests (44 new tests)

This enables real canvas rendering in Happy-DOM when node-canvas is installed:

```typescript
import { HTMLCanvasElement } from 'happy-dom';
import { NodeCanvasAdapter } from 'happy-dom/lib/nodes/html-canvas-element/adapters/NodeCanvasAdapter.js';

HTMLCanvasElement.setCanvasAdapter(new NodeCanvasAdapter());
// Now canvas.getContext('2d') returns real CanvasRenderingContext2D
```

* fix: [#2057] Support Unicode characters in selectors per CSS spec (#2062)

* fix: [#2057] Support Unicode characters in selectors per CSS spec

The CSS specification allows identifiers (class names, IDs, element names)
to contain ISO 10646 characters U+00A0 and higher. The regex patterns in
SelectorParser.ts were only allowing ASCII characters plus a hardcoded
workaround for guillemets.

This change updates both SELECTOR_REGEXP and SIMPLE_SELECTOR_REGEXP to
accept characters in the range \u00A0-\uFFFF, which covers Greek letters,
CJK characters, Cyrillic, Arabic, Hebrew, and other Unicode scripts.

* fix: [#2042] Support CSS gradients with rgba() colors (#2059)

* fix: [#2042] Support CSS gradients with rgba() colors

This fix resolves an issue where CSS background properties containing
linear gradients with rgba() color values would return empty strings.

Root Cause:
- GRADIENT_REGEXP pattern used [^)]+ which stopped at the first closing
  parenthesis, failing to match gradients with nested rgba() functions
- String splitting logic didn't respect nested parentheses, incorrectly
  splitting rgba(0, 0, 0, 0) into multiple invalid parts

Solution:
- Updated GRADIENT_REGEXP to handle one level of nested parentheses
- Improved getGradient() to split commas while respecting parentheses depth
- Added splitByComma() and splitBySpace() helper functions to properly
  handle nested parentheses when parsing CSS values
- Updated getBackground() and getBackgroundImage() to use new helpers

Tests:
- Added 15 comprehensive test cases covering rgba(), hsla(), rgb(), hsl()
- Tests include repeating gradients, conic gradients, multiple gradients
- Tests verify edge cases: many color stops, decimal values, whitespace
- All 7,184 tests pass
