The JIT breakpoint workaround is only needed and only enabled on the Dart side in debug mode. When running --profile mode, the breakpoint is never set and therefore causes the process to hang.

This PR skips the JIT breakpoint workaround for profile mode.

Fixes #185150.

Code Review

This pull request modifies the iOS app launching and LLDB attachment logic to support different build modes. It introduces conditional breakpoint setting and adjusts log pattern matching during process resumption based on whether the build is in debug or profile mode. A review comment identifies an incomplete test case for profile mode in lldb_test.dart that is missing necessary assertions and a closing brace, which would result in a compilation error.

LGTM overall. Thanks Victoria!
