Fix workspace peer-dep, strict-mode, and workspace-range bugs

- checkMissingDependencies: stop flagging workspace-protocol peer
  dependencies as missing from the main app; the redundant OR clause
  bypassed the workspace exclusion filter.
- updateDependencies: strict mode now leaves pinned (non-range)
  versions untouched instead of force-updating them, matching the
  documented behavior.
- getSemverVersion: strip leftover range operators (^, ~, etc.) from
  workspace:-prefixed versions so workspace:^x.y.z and workspace:~x.y.z
  resolve correctly instead of being treated as invalid.
- Remove unreachable duplicate JSON-building branch in displayResults.
- bin/dep-check.js: exit with a non-zero status on unhandled errors
  instead of silently exiting 0.
- index.ts: replace the fragile file-URL string slicing used to detect
  direct execution with a proper pathToFileURL comparison.
