Detect utilities when containing capital letters followed by numbers

[thecrypticace]

Fixes #19463

[coderabbitai]

Walkthrough

A changelog entry was added documenting the detection of utilities containing capital letters followed by numbers (PR #19465). In the NamedUtilityMachine parsing logic, AlphaUpper was added as a valid preceding classification for Number tokens, allowing capital letters to precede numeric sequences (e.g., text-titleV1-strong). The test suite was updated to include a corresponding test case validating the new extraction behavior.

Check name	Status	Explanation
Title check	✅ Passed	The title clearly and accurately describes the main change: detecting utilities with capital letters followed by numbers in utility names.
Description check	✅ Passed	The description references the fixed issue (#19463), which is relevant to the changeset addressing mixed-case parent keys in nested color objects.
Linked Issues check	✅ Passed	The code changes in the NamedUtilityMachine parser update the logic to accept capital letters preceding numbers in utility names, directly addressing issue #19463's requirement to support mixed-case keys like iosV3.
Out of Scope Changes check	✅ Passed	All changes are focused on the named utility machine parsing logic and corresponding test cases, directly scoped to fixing the capital letter + number detection issue.

CHANGELOG.md (1)

15-15: Changelog entry correctly documents the extractor fix

The new “Detect utilities when containing capital letters followed by numbers” bullet is accurate, scoped, and consistent with existing changelog style. No changes needed.

crates/oxide/src/extractor/named_utility_machine.rs (1)

279-304: Allow numbers after uppercase letters to support mixed‑case segments

Including Class::AlphaUpper in the valid predecessors for Class::Number fixes parsing of sequences like V1 in text-titleV1-strong while keeping the rest of the numeric rules intact (next-char checks unchanged, start state still disallows uppercase-only utilities). The added test case for text-titleV1-strong correctly exercises this path and guards against regressions. No further changes needed.

Also applies to: 427-430
