Kazuki Yamada e5f7a1f311 fix(shared): Address PR review feedback
- shared/errorHandle: recognize duck-typed OperationCancelledError from
  worker boundaries in isRepomixError (it extends RepomixError but the
  name was missing from the structured-clone fallback comparison).
  Add a regression test for the worker-boundary case.

Test improvements per coderabbit / claude review:
- cliReport: assert skill-directory + relative path on the same log line.
- processConcurrency: restore process.versions.bun by removing the property
  when it didn't originally exist, instead of leaving it defined-as-undefined.
- logger: drop the no-op `process.env.REPOMIX_LOG_LEVEL = undefined` (it
  coerces to the string "undefined" and is overwritten by the next delete).
- unifiedWorker: replace the tautological cache test with one that proves
  cache uniqueness via onWorkerTermination cleanup count; add a test for
  task-based inference overriding workerData (bundled-env reuse).
- calculateMetricsWorker: new direct test for the default export's items
  vs. single-mode dispatch — unifiedWorker mocks this module so the branch
  was otherwise untested.
- packRemoteRepositoryTool: hard-code the expected output path instead of
  expect.any(String) to catch arg-swap regressions.
- memoryUtils: tighten getMemoryStats assertions with sanity bounds
  (heapUsed <= heapTotal, rss > 0, heapUsagePercent <= 100) so a
  unit-conversion regression (bytes vs MB) would fail the test.
