feat(kernel): R7b Lua+Luau walker — one lua module, vendored-grammar-C lua v0.4.1, tree-sitter-luau 1.2.0 pin, both default-routed (#1384)
R7b batch 4 #2 (docs/design/lua-luau-kernel-port-checklist.md is the authoritative quirk list). ONE walker for both dialects (ccpp precedent) — the differences are exactly four: luau's type_definition aliases, the `export `-slice isExported hook, the return-type signature suffix, and the grammar handle. Grammar prep is kernel-side only, no wasm change: lua is the SECOND vendored-grammar-C language (the vendored wasm is the v0.4.1 tag, a revision not on crates.io — tag artifacts compiled via build.rs, shas pinned); luau is a plain crate pin =1.2.0 whose tarball is sha-identical to the tag (the swift tag≠crate divergence does not recur). Grammar-parity rows replace the bump gate entirely. Preserved bug-for-bug (all probe-pinned): the require/visitNode-hook ASYMMETRIES (top-level requires — including inside top-level if/for/while — mint import nodes while the identical body-level statement emits `calls "require"`; top-level `local x = foo()` initializers are invisible while global `x = foo()` calls emit), the BFS string-win inside require args (`require(script:WaitForChild("Kid"))` → import Kid) and Roblox instance paths, receiver-QN methods (`M.sub.deep::chained`, `_G::installed`, stack-QN nested globals like `render::leakedGlobal`), the raw-text callee world (colon forms with `self` never stripped, bracket callees, newline-glued chains byte-verbatim, the `(handler)` paren-conversion), LUA_SPEC function-as-value capture with the `M.cb = cb` param-storage skip and first-occurrence dedupe, LuaDoc `---` keeping a leading `- ` plus `--!strict` joining docstring chains (block-comment docstrings keep interior CRLF bytes), variable nodes at the IDENTIFIER with positional value pairing, duplicate same-(kind,name,line) ids, and the lua↔luau isExported wire divergence (lua functions: flag absent; luau functions: present-false; methods: absent in both; variables: present-false in both; `export type`: true). Gates: parity sweeps first-run 0-diff on kong/lazy.nvim/lua-resty-core (lua) + lune/Fusion (luau) — 1,734 clean files byte-parity, deferrals 1/0/0/3/8 matching the survey's both-arm predictions exactly (kong's 1 = a deliberately invalid fixture; luau's = grammar-inherent generic type packs and default type params); full-init dumps byte-identical kernel-vs-wasm ×4 (kong 157,650 dump lines); kernel-lua-parity suite (both torture fixtures + in-memory CRLF variants + glue-chain, duplicate-id, and cross-dialect defer pins + kernel-arm wire-flag pins); full suite 2,647 green ×2 with CODEGRAPH_KERNEL_EXPECT=1. DEFAULT_ROUTED += lua, luau (18 langs). Co-authored-by: Claude Fable 5 <noreply@anthropic.com>
