Bump netsuite-suitecloud to upstream HEAD and add 4 Oracle skills

Bumps the pinned SHA (43bacf4 -> cbfc8e8, oracle/netsuite-suitecloud-sdk
master) and expands the skills array to include four skills Oracle has
added upstream since the original consolidation:

  - netsuite-owasp-secure-coding
  - netsuite-sdf-project-documentation
  - netsuite-suitescript-records-reference
  - netsuite-suitescript-upgrade

Validated locally with `claude plugin validate` (passes). Author: Oracle
NetSuite (UPL-1.0). Opened manually because the SHA-bump automation skips
skills-only git-subdir entries that have no literal plugin.json.
