refactor: remove unused rate-limit helpers and improve PowerShell scripts

- Remove unused _parse_rate_limit_headers() and _format_rate_limit_error()
  from src/specify_cli/__init__.py (56 lines of dead code)
- Add GENRELEASES_DIR override support to PowerShell release script with
  comprehensive safety checks (parity with bash script)
- Remove redundant shared-file update calls from PowerShell agent context
  script (AMP_FILE, KIRO_FILE, BOB_FILE, FORGE_FILE all resolve to AGENTS.md)
- Update test docstring to accurately reflect Forge's {{parameters}} token

Changes align PowerShell scripts with bash equivalents and reduce maintenance
burden by removing dead code.
