- Add merge mode options: add to existing or replace all
- Move Toaster to builder.tsx for proper z-index layering
- Use 'old'/'new' field names to match SDK PageRedirect schema
- Include 107 comprehensive tests for parser

- Move description text into info tooltip for cleaner UI
- Update OldPagePath schema to allow Unicode/UTF-8 characters
  (Chinese, Japanese, Korean, Cyrillic, Arabic, Hebrew, Thai, Greek, etc.)
- Only disallow truly problematic URL characters (spaces, <, >, ", {, }, |, \, ^, `, [, ])
- Add comprehensive tests for non-Latin character support in paths
- Update existing tests to use new error message format

Verify that the URLPattern-based router correctly handles:
- Chinese (Simplified & Traditional)
- Japanese (Hiragana, Katakana, Kanji)
- Korean (Hangul)
- Cyrillic, Arabic, Hebrew, Greek
- European diacritics (über, café, niño)
- Dynamic segments capturing non-Latin characters
- Wildcard patterns with non-Latin paths
- URL-encoded to literal decoding

Verify generateRemixRoute correctly handles:
- Chinese (关于我们, 产品/手机)
- Japanese (日本語, ブログ/記事)
- Korean (한국어)
- Cyrillic (привет, блог/статья)
- European diacritics (über-uns, café)
- Mixed Latin and non-Latin paths

Note: React Router handles URL decoding at runtime to match
encoded URLs against Unicode filenames.

Creates a shared test data module (redirect-path-test-data.ts) that defines:
- VALID_REDIRECT_PATHS: categorized valid paths (basic, patterns, non-Latin, etc.)
- INVALID_REDIRECT_PATHS: categorized invalid paths (spaces, unsafe chars, etc.)
- VALID_URLPATTERN_PATHS: paths suitable for URLPattern testing
- STATIC_PATHS: non-pattern paths for route generation testing

This ensures all three layers are tested with the same path data:
1. OldPagePath schema validation (SDK) - 67 tests
2. URLPattern matching (builder) - 174 tests total
3. Route generation (react-sdk) - 113 tests total

When a new path type needs support, add it to redirect-path-test-data.ts
and all layers will automatically be tested for consistency.

These test utilities validate router paths in general, not just redirects:
- Pages, redirects, and any routable URLs all use the same path rules
- URLPattern matching is used for all page routing in the builder
- Route generation is used for all pages on published sites

Renamed:
- redirect-path-test-data.ts → router-path-test-data.ts
- redirect-paths.test.ts → router-paths.test.ts
- VALID_REDIRECT_PATHS → VALID_ROUTER_PATHS
- INVALID_REDIRECT_PATHS → INVALID_ROUTER_PATHS
- @webstudio-is/sdk/redirect-paths.test → @webstudio-is/sdk/router-paths.test

When clicking outside the combobox, don't reset the typed value.
Only update when onChange receives an actual value, not undefined.

Move from project-settings/redirect-parsers to shared/redirects
so it can be used by both project settings and page settings.
