gofmt: format all remaining files with the go1.27 toolchain

The tree was formatted with an older gofmt; go1.27's gofmt additionally
wants: EOF exactly one newline (no trailing blank lines), imports sorted
alphabetically within a block, mixed-precedence binary expressions
re-spaced for grouping ((a+b)/c), single-field composite literals
un-aligned, adjacent one-line method signatures aligned, and one-line
bodies containing a compound statement expanded. Applied repo-wide
(31 files under internal/); pure formatting, no semantic changes —
build and the full test suite pass.
