chore: finalize #7185 maintainer landing metadata

[proggeramlug]

#7185 landed while this same-repository maintainer branch was being prepared. The contributor commit correctly omitted release metadata, so this follow-up supplies the required 0.5.1277 patch bump and keeps the remaining scalar-root comments and panic diagnostics consistent with js_shadow_frame_enter.

It also resolves the review wording nit without changing the already-landed fixture assertions.

Verification:

• cargo test -p perry-codegen --test scalar_replaced_slot_roots (11/11)
• cargo fmt --all -- --check
• git diff --check

Follow-up to #7185.
