tools/port_report.py turns a diff into work items: rank 1 blocks the switch (facts,
packets, DataFixers, data component types, report formats, tables to regenerate),
rank 2 and 3 one item per Horizon file that ports changed vanilla code (with or
without a harness), rank 4 new content, rank 5 summaries. version_port.py report
writes report.md and report.json; port prepares, diffs and reports in one go.
The class map now resolves names of both versions. The doc records the 26.2 -> 26.3
replay against Horizon's own code.

tools/class_index.py hashes every method's bytecode with constant-pool references
resolved and branch targets as instruction indices, lambdas folded into their
declaring method; class diffs list moved classes. tools/vanilla_map.py maps vanilla
classes to the Rust files whose comments name them and the harnesses whose oracles
or probes reach them. version_port.py prepare indexes, diff reports both.

detect reads Mojang's manifest; prepare downloads and verifies a version into the
version store (outside the repository), runs its data generator and reads the
jar's own version facts; diff compares facts, packets, registries, blocks, item
components, commands, data packs, assets and lang.
