installRuntimeModuleResolver patched Module._resolveFilename process-wide
with no way back. In the shared bun test process the leaked patch broke
createRequire relative requires for every later test file (Bun 1.3.14 calls
a JS _resolveFilename override with parent === undefined, so './x' resolves
'from ""'), failing legacy-pi-inplace-load only in full-suite runs.
The installer now returns an uninstaller that drops the registration and
restores the pristine resolver when no runtime roots remain; the known Bun
limitation is documented so the patch stays scoped to worker runtimes.
