What and why

The UUID inspector rejected a GUID in braces ({3f2504e0-...}, as .NET and the Windows registry show them) and a urn:uuid: value, because inspectUuid() tested the trimmed text against UUID_PATTERN before anything else. It now drops a leading urn:uuid: (any case) or one pair of surrounding braces first, then checks and decodes the rest as before. Unbalanced or doubled braces, braces after urn:uuid:, and other prefixes stay invalid.

The UUID guide said braces are reported as invalid, and its example test pinned that, so I updated that line to say both forms are accepted and changed the test to match.

Closes #414

How I tested this

• Added cases to lib/__tests__/uuid.test.ts: braces, urn:uuid:, URN:UUID: and surrounding whitespace each inspect the same as the bare UUID, and five malformed wrappers stay invalid. The 4 accepting cases fail without the change.
• npm run lint: 0 errors, the same 11 warnings as on develop.
• npm run test: 64 files, 2435 tests pass.
• npm run build: passes.
• npm run dev, /uuid-generator: the bare value, {...} and urn:uuid:... all show Version 4 and Variant RFC 9562, and {... without the closing brace shows no result.

Thanks @prakashNalla. Lint (develop's 11 warnings), all 2435 tests, the build and the pages pass on top of develop. Braces and urn:uuid: (any case, with spaces around) now inspect like the bare UUID, while {abc..., double braces, urn:uuid:{...} and a bare uuid: prefix stay invalid, and good catch updating the guide line that told people to remove the braces.
