fix: title react-hooks-js/todo diagnostics as unsupported syntax

[devin-ai-integration]

Summary

Every adopted React Compiler diagnostic got the same "React Compiler can't optimize this" headline. But the compiler's todo rule isn't an optimization miss in the user's code — it fires when the compiler bails out on syntax it doesn't handle yet (e.g. (BuildHIR::lowerExpression) Handle TaggedTemplateExpression expressions), so the generic headline misattributed the problem.

resolveDiagnosticTitle in core/src/runners/oxlint/parse-output.ts now special-cases the rule:

plugin === "react-hooks-js"
  rule === "todo" → "React Compiler doesn't support this syntax"
  otherwise      → "React Compiler can't optimize this"

Message/help/category are unchanged; only the headline differs. Covered by an inline-snapshot test of the full parsed Diagnostic for a react-hooks-js(todo) finding plus a guard that other react-hooks-js rules keep the generic headline (packages/core/tests/react-compiler-diagnostic-title.test.ts). Changeset included (patch).

Low Risk
User-facing copy only in oxlint diagnostic title resolution; no scan logic or scoring changes.

Overview
React Compiler todo diagnostics now show the headline "React Compiler doesn't support this syntax" instead of the shared "React Compiler can't optimize this" string. That matches cases where the compiler bails on syntax it does not handle yet (the react-hooks-js/todo rule), rather than implying the user’s code failed optimization.

resolveDiagnosticTitle in parse-output.ts branches on rule === "todo" for react-hooks-js; message, help, and category are unchanged. Tests cover the todo title via an inline snapshot and assert other react-hooks-js rules still use the generic headline. Patch changeset included.

Test results

Ran the branch CLI end-to-end against a fixture project (babel-plugin-react-compiler in devDependencies, new.target in a component to force a compiler Todo bail-out, plus a ref.current-during-render control).

• react-hooks-js/todo diagnostic carries title: "React Compiler doesn't support this syntax" — passed
• react-hooks-js/refs diagnostic keeps title: "React Compiler can't optimize this" — passed
• Terminal renderer shows the new headline — passed
• Snapshot test + existing parse-output tests (9 total) — passed
• CI green (19/19)
