  -----------
  [clang-format] Fix crash on assert !Scopes.empty() in parseBrace() (#199100)

Fixes #199017

When angle-bracket parsing fails and resets the token stream, a closing
brace can be consumed twice through `parseConditional()`, each time
popping one entry from Scopes. This leaves Scopes empty when
`parseBrace()` encounters the legitimate closing brace, triggering the
assertion.

Replace the assert with a graceful return false, consistent with the
existing unbalanced-brace handling in `consumeToken()`.
