Add Move language support (Sui, Aptos, Movement)

[poelzi]

Summary

Adds support for the Move smart-contract language, used by Sui, Aptos, Starcoin, and Movement. .move files are currently silently ignored by scc.

A single language definition covers every dialect — Move 2 (Aptos) is a lexical superset of core Move, and Sui only adds the entry modifier; no dialect renames or removes a keyword in a way that would confuse a tokenizer.

Notable choices:

• nestedmultiline: true — Move's lexer (move-compiler/src/parser/lexer.rs) explicitly tracks nested /* /* */ */ comments via a stack, like Rust.
• Complexity checks mirror the existing Rust entry plus match (Move 2) and abort — Move's panic primitive, used on every error path.
• b"..." and x"..." byte/hex string prefixes work transparently because string parsing begins at the ".

Test plan

• go generate ./... regenerates processor/constants.go with the new entry
• go build compiles cleanly
• go test ./... passes (including TestSpecificLanguages, which greps CSV output of examples/language/)
• scc examples/language/move.move reports correct counts: 32 lines, 3 comments (nested block correctly counted as one region), complexity 8

Thanks for this. Will make the next release.
