[Milestone A] A-03: Whitespace preservation regression tests

[csharpfritz]

Milestone A — Parser Hardening (A-03)

Priority: P0
Size: Small
Branch: experiment/aspx-middleware
File: src/BlazorWebFormsComponents.AspxMiddleware.Test/AspxParserWhitespaceTests.cs (new)

Deliverable

Write unit tests that parse ASPX fragments where whitespace between controls is significant and verify that \AspxTextNode\ instances with whitespace content are present in the resulting AST.

Test Cases

• Single space between inline elements
• Newline between block elements
• Multiple spaces (preserved as-is)
• Mixed whitespace (\r\n, tabs)
• Whitespace inside ContentPlaceHolder regions

Depends On

• A-01 (whitespace fix must land first, or tests will fail)

Context
