Parallelize compression and optimize memory allocations

  • Parallelize docs and metas compression in DocsMetasCompressor using goroutines
  • Pre-allocate 1MiB capacity for binaryDocsPool and binaryMetasPool to reduce allocations
  • Skip zero-value metric increments in MergeQPRs when repetitionsCount is 0
  • Fix partial indexing logic in keyword/path/text tokenizers: now correctly truncating oversized values instead of always discarding the tail without partial indexing
  • I have read and followed all requirements in CONTRIBUTING.md;
  • I used LLM/AI assistance to make this pull request;
