feat(publish): upload findings from CSV

[kmbroai]

Summary

Allow Cloud publication to ingest the existing Codex Security findings CSV format, so exported or manually assembled findings can be validated and uploaded without a completed scan directory.

Changes

• Add --csv PATH to codex-security publish scan --to cloud.
• Validate standard and Deep Scan CSV fields before authentication or upload.
• Preserve --dry-run --json as a local preview with no login or network request.
• Add a header-only template at examples/findings.csv.
• Preserve source IDs and triage metadata while producing canonical upload findings.

Testing

• Focused Cloud publisher and CLI tests, seed 12345: 73 passed
• pnpm run types
• pnpm run format
• pnpm run build
• git diff --check

The affected suites pass. The repository-wide suite was not used because unrelated output-ancestry tests reject the temporary worktree parent before reaching this feature.

Risk and rollout

This is an additive CLI option. Existing scan-directory and Linear publication behavior is unchanged. Invalid CSV input fails before credentials are read or a request is made. No server changes are included or expected.

Public disclosure review

• No customer, partner, prospect, or user identities, data, or identifying details are included.
• No credentials, personal data, private source, scan findings, or nonpublic links or tickets are included.
• I reviewed the branch name, title, description, commits, changes, comments, logs, screenshots, attachments, and links for public disclosure.
