Greptile Summary

This PR adds a Key Pair authentication section to the Snowflake integration docs and reorganises the existing OAuth steps under an ## OAuth heading. The new section covers key generation, Snowflake user setup (including the required GRANT ROLE), fingerprint verification with the correct SHA256: prefix note, and env-var configuration.

• Key-generation commands (openssl genrsa | openssl pkcs8 -topk8) and the public-key derivation step are correct; both unencrypted and passphrase-protected variants are shown.
• The SQL block correctly includes GRANT ROLE <role> TO USER svc_reflex; and explains that DEFAULT_ROLE alone is insufficient.
• The fingerprint verification pipeline (openssl rsa -pubin … | openssl dgst -sha256 -binary | openssl enc -base64) matches Snowflake's SHA-256 over DER-encoded SubjectPublicKeyInfo, and the doc properly notes Snowflake prepends SHA256: to the stored value.

Confidence Score: 5/5

Documentation-only change; all shell commands and SQL are technically accurate and safe to merge.

The change is a documentation addition. Every openssl command, the SQL DDL, the fingerprint verification pipeline, and the env-var names are technically correct. The two issues previously identified in review (missing GRANT ROLE and the SHA256: prefix on the fingerprint) are both addressed. No code paths are affected.

No files require special attention.
