Add CL_9900001 (oRGC5) term for retinal ganglion cell orthotype

[Copilot]

Plan for creating oRGC5 term (CL_9900001)

• [x] Understand the repository structure and how terms are defined
• [x] Locate the parent term (CL_0000740 - retinal ganglion cell)
• [x] Review similar terms (OFF parasol ganglion cell - CL_4033051) for pattern
• [x] Create new term CL_9900001 with:
  • Declaration: Declaration(Class(obo:CL_9900001))
  • Label: oRGC5
  • Definition with inline PMID references: "(Hahn et al., 2023, PMID:37066415; Tran et al., 2019, PMID:31784286)"
  • SubClassOf relationship to CL_0000740 (retinal ganglion cell)
  • Creator annotation (GitHub Copilot)
  • Contributor ORCID annotation (https://orcid.org/0000-0002-5507-2103)
  • Date annotation (2025-12-08T11:46:13Z)
• [x] Validate the ontology syntax with robot convert
• [x] Validate reasoning with robot reason
• [x] Run code review and address feedback
  • Fixed non-standard en dash character to standard hyphen
• [x] Run security checks (no code vulnerabilities found)
• [x] Address PR comment: Added PMID references inline within definition text
