fix(visit): panic on invalid AST paths (#12154) **Description:** `swc_visit::wrong_ast_path` used unchecked unreachable behavior behind a safe function, allowing invalid public AST-path states to trigger undefined behavior in optimized builds. This change: - retains the existing safe `wrong_ast_path()` signature for compatibility with published visitor crates; - makes invalid AST paths panic deterministically in debug and release builds; - adds regression coverage for the safe call; - removes the now-unused `new_debug_unreachable` dependency; and - avoids unrelated visitor regeneration, preserving the CSS, HTML, and XML hook APIs. Validation: - `cargo test -p swc_visit` - `cargo test --release -p swc_visit wrong_ast_path_panics` - `cargo clippy -p swc_visit --all-targets -- -D warnings` - `cargo fmt --all` The full workspace Clippy baseline reached the affected visitor crates but could not complete because this hosted runner disables submodule initialization; the absent HTML5Lib fixtures cause the HTML parser fixture macros to report `No test found`. **Related issue (if exists):** Closes #12082 --------- Co-authored-by: Labor0 Bot <279936132+labor0-bot[bot]@users.noreply.github.com>

fix(es/typescript): Keep mutable ambient enum reads opaque A plain ambient enum is a runtime object that can be reassigned like any other non-const enum, but the ambient-record fallback resolved its members unconditionally: under `tsEnumIsMutable`, an enum member reading one was folded to the declared value while every other read of it stayed a runtime read. Gate the ambient fallback — in member lookup and in the sibling arm — on the const-enum rule the option already applies elsewhere. The primary record is untouched: how concrete enum reads behave under the option predates this PR and is tracked in #12151.
