Remove `tryRecord()` from the compilation pipeline now that all passes record errors directly via `env.recordError()` / `env.recordErrors()`. A single catch-all try/catch in Program.ts provides the safety net for any pass that incorrectly throws instead of recording. Key changes: - Remove all ~64 `env.tryRecord()` wrappers in Pipeline.ts - Delete `tryRecord()` method from Environment.ts - Add `CompileUnexpectedThrow` logger event so thrown errors are detectable - Log `CompileUnexpectedThrow` in Program.ts catch-all for non-invariant throws - Fail snap tests on `CompileUnexpectedThrow` to surface pass bugs in dev - Convert throwTodo/throwDiagnostic calls in HIRBuilder (fbt, this), CodegenReactiveFunction (for-in/for-of), and BuildReactiveFunction to record errors or use invariants as appropriate - Remove try/catch from BuildHIR's lower() since inner throws are now recorded - CollectOptionalChainDependencies: return null instead of throwing on unsupported optional chain patterns (graceful optimization skip) --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.com).
