Add masked logging for collection search payloads

Introduces masking utilities across the search planning types so that request data can be logged without exposing user content. Server-side tracing for collection_search now records only masked payloads, and a unit test asserts that sensitive strings are fully removed while structural hints remain.

Key Changes

• Adds SearchPayload::masked and delegates to new masked helpers on Filter, Rank, RankExpr, QueryVector, Where, and MetadataComparison to anonymize values while retaining shape metadata.
• Extends MetadataComparison::masked to preserve the original comparison variant, converting boolean sets to integer-length placeholders and replacing other value types with neutral stand-ins.
• Updates collection_search tracing to emit masked payloads instead of raw queries and introduces test_search_payload_masked_hides_sensitive_info to verify behavior.
