Pier 26.40.3

Fixed

• lip install produced a mod directory LeviLamina refuses to load. The release
  archive kept the packer's output directory as an extra level, so the package installed
  as plugins/pier/Pier/. LeviLamina scans one level under plugins/, finds no
  manifest.json in plugins/pier/, and Pier is never loaded.

  Two things were wrong and both are fixed. tooth.json placed the whole archive root
  into plugins/pier/ instead of placing the mod directory into plugins/Pier/. And the
  release workflow tried to strip the wrapping directory by testing for a literal pier,
  which is silently false on a case-sensitive runner where the packer writes Pier.

  The packaging step now finds the mod directory by the manifest.json it holds, renames
  it to the name that manifest states, and refuses to publish an archive whose root is not
  that directory with its dll and its lang/ beside it. The folder name is not cosmetic:
  ModRegistrar.cpp compares it against the manifest name as a std::string, so pier
  and Pier are two different mods and one of them does not exist.

• manifest.json named pier.dll while the build produces Pier.dll. Windows
  resolves it either way, which is why it went unnoticed; it now says what the file is
  called.
