fix(ci): exclude docs from secret scanning and skip interactive script validation

- Security checks: Exclude docs/ and examples/ from secret pattern matching
  (prevents false positives on documentation examples)
- Install validation: Skip bash -n check for scripts using /dev/tty
  (interactive scripts are valid but fail non-interactive syntax checking)

Fixes workflow failures in dev-to-main PRs.
