Stacked on #3 (`release/streamcount-validation`), which is stacked on #2. Completes the remaining public declarations and distributed-package validation, and prepares version 2.0.0. Declarations cover every root export and the existing CountMinSketch, HyperLogLog, MinHeap and PRNG deep imports. Tests install the tarball independently, exercise CommonJS/ESM, and compile positive/negative NodeNext and Node16 TypeScript consumers. The package includes its format/migration documentation. Tests run before publishing; no automatic publishing is configured. Validation: 37 tests pass locally, including the signed-minimum hash regression and all parent serialization/estimator tests. CI installs the development dependencies on Node 22/24/26 and adds a separate Node 6 runtime-floor smoke test. Removes the obsolete Travis matrix identified by the review of #2. npm publication and merging are not performed by this PR. Stacked follow-up: #6 adds validated weighted increments, superseding #1. Merge this PR before #6.

Stacked on #4. Supersedes #1's weighted-increment proposal, originally contributed by Ruslan Dzhumakaliev, with `increment(key, incrementBy = 1)` and public TypeScript declarations. Accept nonnegative uint32 integer weights; zero is a no-op, and invalid weights or counter overflow reject before mutation. Raise all selected buckets below the new minimum rather than only the old minimum buckets. For example, buckets 5 and 7 become 15 and 15 after +10, matching ten unit conservative updates; the original proposal produced 15 and 7 while reporting 15. Add collision-heavy comparisons against repeated unit updates, top-k checks, uint32 boundary/atomicity checks, legacy/CMS2 roundtrips, installed TypeScript consumer coverage and a Node 6 weighted-update smoke check. Document that weighted observations do not implement full distributed sketch merging or recover keys omitted from workers' top-k lists. Validation: all 44 tests pass locally. CI covers Node 22/24/26 and the Node 6 runtime floor. No merge or publication is performed; #1 can be closed as superseded once this replacement is accepted.

This new functionality serves the purpose of performing count-min sketch computation in distributed environment where output of multiple workers/mappers (map/reduce) needs to be merged into and aggregated centrally by reducer
