What

chmod and chown mock overrides now update ctime on the target file, matching real filesystem behavior.

Why

Real chmod(2) and chown(2) both update the inode change time (ctime). The mock implementations were missing this update, causing stat() to return stale ctime values. This is part of issue #70 (more realistic stats).

How

Added $mock->{'ctime'} = time after each successful mode/ownership change in both __chmod and __chown.

Testing

  • Added "chmod updates ctime" subtest to t/chmod.t
  • Added "chown updates ctime" subtest to t/chown.t
  • Both use sleep 1 to ensure measurable time difference
