Feat/finmmtl 310 add multi relative filters

[garethj2]

Add relativizeOn support for customizing relative Haystack filters. This work introduces a new relativizeOn mechanism that allows records to define their own preferred tags for relativization, replacing the previous hardcoded logic in src/filter/util.ts.

Key changes:

• New src/filter/relativize.ts module replaces src/filter/util.ts
• Records can now define a relativizeOn tag (HList of HStr) to specify which tags should be used when generating relative filters
  • Supports special expansion identifiers:
    • {dis} — expands to the first available display name tag (dis, name, tag, or navName)
    • {markers} — expands to all marker tags on the record
    • {kind} — expands to the kind tag for point records
• New makeRelativeHaystackFilterForTarget() function generates relative filters for a target record by traversing the containment hierarchy
• Supports resolveCache for efficient resolution across multiple calls
• New options: useRelativizeOn, includeIntermediateRecords, includeTargetMacro, resolve, resolveCache, and prefixPath
• Comprehensive test coverage for all new functionality
