Needs: the owner of the untracked tools/comptime_bundle.nika (and lowered/comptime_bundle.rs) must fix or remove it; it breaks cargo build -p nikaia-std (E0119 CheckWall Display in grammar_run.rs, E0592 duplicate message, E0277 PathBuf From EitherText)

Body: the edit is in the working tree, uncommitted, in emit_core_leaves.nika (and its lowered twin): the hole-less branch replaces “{{“ with “{“ and “}}” with “}” in format_of(parts) before writing the literal. The test fstring_no_hole_braces.nika is not kept; its content was the probe, f”{{}}”.len(), and a hole-less f-string with " and \ as receiver.
