Duy /zuey/ 7d7b716074 fix(tools): quote-aware shell operator detection in credentialed exec (#700) (#702)
* fix(tools): quote-aware shell operator detection in credentialed exec (#700)

- Replace detectShellOperators with detectUnquotedShellOperators in
  credentialed exec path — respects single/double quoting so that
  characters like | inside argument values (e.g. --jq '.[0] | .name')
  are not falsely flagged as shell operators
- Pass raw command string (preserving quotes) to executeCredentialed
  instead of reconstructing from parsed args
- Downgrade "no credential found" log from Warn to Debug (fires for
  every non-credentialed command, too noisy at Warn)
- Add extractUnquotedSegments() helper with comprehensive tests

* fix(tools): handle backslash escape outside quotes in shell operator detection

extractUnquotedSegments did not handle \ as an escape character outside
of quotes, causing \" to incorrectly enter double-quote mode. This hid
subsequent shell operators from detection (e.g. gh \"arg\" | env would
not detect the unquoted pipe).

Add backslash escape handling in the unquoted state to match
go-shellwords parsing behavior. Both \ and the escaped character are
emitted as unquoted content so operator detection still catches them.
