* fix(smartplaylist): support isMissing/isPresent operators on ReplayGain fields ReplayGain values are stored in dedicated nullable columns (rg_album_gain, rg_album_peak, rg_track_gain, rg_track_peak) rather than in the media_file.tags JSON blob. The isMissing/isPresent operators previously only supported tag and role fields, causing two failure modes: 1. Using the documented alias names (replaygain_album_gain etc.) from PR #5256: these got registered as JSON tags from mappings.yaml, so isMissing queried json_tree(media_file.tags, '$.replaygain_album_gain') which is always empty -> the playlist matched ALL songs. 2. Using the canonical field names (rgalbumgain etc.): not a tag/role, so SQL generation returned an error. Because refreshSmartPlaylist deletes old tracks before regenerating, the abort left the playlist empty. Fix: add Nullable bool to FieldInfo and mark the four ReplayGain fields. Add static alias entries (replaygain_album_gain -> rgalbumgain etc.) with Numeric+Nullable set; because AddTagNames skips names already in the field map, these static entries take precedence over the mappings.yaml tag registration. missingExpr now emits IS NULL / IS NOT NULL for nullable column fields instead of the json_tree lookup. Fixes #5584 * chore(smartplaylist): address code review feedback - Simplify the isMissing/isPresent unsupported-field error message, removing the internal "nullable fields" jargon - Standardize comments on mappings.yaml (the actual filename) - Clarify the alias precedence comment in the LookupField test
