Pull request overview

Refactors the TypeScript-to-Lua try/catch/finally transformation to correctly handle control flow (return/break/continue) across try, catch, and finally blocks. Previously, finally did not behave correctly with respect to control flow (see #1137), and break/continue inside try were only handled in async contexts.

Changes:

• Rewrote transformTryStatement to wrap both try and catch in pcall, using a unified ____hasReturnOrError flag so finally can override returns and errors can be re-thrown after finally executes.
• Generalized the try-scope break/continue flag handling (previously asyncTryHas*) to apply to all try/catch blocks, not just async ones; renamed findAsyncTryScopeBeforeLoop → findTryScopeBeforeLoop and asyncTryHas{Break,Continue} → tryHas{Break,Continue}.
• Added extensive unit tests covering returns from try/catch/finally, throws from finally, and break/continue inside try/catch with and without finally; un-skipped the re-throw test (#1137).
