Add meaningful verification to liberty ECSM, sky130 corners, writer,
and roundtrip tests. Expand verilog specify, escaped-write, remove-cells,
write, and writer tests with content checks, roundtrip validation, and
error guards. Update corresponding .ok golden files.

Remove useless empty-body if-blocks that check file size/existence without
doing anything, replacing them with meaningful puts output where appropriate.
Split monolithic verilog test files into individual per-test files with
their own .ok golden files. Update .ok files to match actual output.
