False positive: "Builtin" wrongly flagged to change to "Built in" where it should be "Built-in"

**What got flagged?**

**Builtin WebUI**: Builtin web UI to manage your bot.

**Why is this incorrect?**

Here "Builtin" is not actually a compound noun, but a compound adjective. Compound adjectives should be hyphenated when used attributively, which means before the noun they describe, in this case "WebUI" an "web UI".

We have a separate linter for "built-in" but it seems not to be triggered here, or is perhaps overridden?

Reproduce the report with “Builtin WebUI” and inspect the separate “built-in” linter and the rule that flags “Builtin” as “Built in.” Done means the compound adjective is handled as “Built-in” without producing the incorrect replacement warning.
