fix(es/parser): Keep recoverable errors from speculative TypeScript parses `try_parse_ts` set `Context::IgnoreError` for the whole speculative parse and only restored it afterwards, so every recoverable error emitted while building the AST was dropped even when the parse succeeded and its AST was kept. `export namespace Foo {` with no closing brace therefore parsed without a single diagnostic, while `namespace Foo {` correctly reported `Expected '}'`. `LexerCheckpoint` now records the length of both error buffers and truncates them in `checkpoint_load`, the same way `CapturingCheckpoint` rolls back captured tokens. With rollback available, `try_parse_ts` and `try_parse_ts_bool` no longer suppress errors: a discarded speculative parse discards its errors along with the rest of the checkpoint, while a kept one keeps them. Flow still suppresses, because it reports `_` in a type argument list as an error even where Flow allows it and un-suppressing surfaces those false positives. `parse_ident` no longer reports strict mode reserved words inside a type position. Parameter names of a function type are not bindings, so `(package: Package) => void` is valid; this was already reported for non-exported interfaces and was only hidden for exported ones by the suppression removed above.
