docs: update adapter table — add missing copilot, codex, kiro, gitclaw (#78)

README adapter table listed 12 adapters but export.ts supports 15.
Added: copilot, codex, kiro (export-only) and gitclaw.
Also corrected github description from 'GitHub Actions' to
'GitHub Models inference' to match actual implementation.
