Fix documentation issues from PR review

- Remove non-existent COPILOT_LOG_LEVEL env var references (SDK doesn't read it)
- Fix Python log directory example (cli_args doesn't exist in Python SDK)
- Add note about Python/Go limitation for log directory config
- Add initialPrompt field to SessionStartHookInput docs
- Add finalMessage and error fields to SessionEndHookInput docs
- Fix SessionEndHookOutput fields (suppressOutput, cleanupActions, sessionSummary)
