In build_update, Hash values were interpolated directly into the query string without sanitization, allowing N1QL injection. Use quote() to properly escape values. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Code Review
This pull request updates the Couchbase ORM relation builder to properly quote hash values when constructing update queries. The review feedback highlights a potential N1QL syntax error when a value is nil, as the quoted value would interpolate to an empty string, and suggests adding a fallback to 'NULL'.

When a nil value is passed in a Hash update (e.g. update(field: { key: nil })),
quote() returns nil which interpolates as an empty string, producing invalid
N1QL syntax. Fall back to 'NULL' literal in that case.

Cover string values, nil values, and special character quoting in Hash-style update_all to verify the N1QL injection fix. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

In
Relation#build_update, when updating nested Hash attributes (e.g.update_all(address: { city: user_input })), the value was interpolated raw into the N1QL query string. This allowed N1QL injection through crafted values.Test plan
