Move all ten ISA packages (x86, arm32, arm64, mips, riscv, ppc, ppc_vle, rsp, mos6502, mos65816) from core/rexcode/<arch> to core/rexcode/isa/<arch>, so the import pattern is now `import "core:rexcode/isa/x86"`. The shared core stays at core:rexcode/isa. Mechanical: relative `import "../isa"` / "../../isa" -> absolute "core:rexcode/isa" (the only path that survives the move; the "../" and "../.." self/generated imports move with their packages). build.lua now builds paths as <root>/isa/<name>; stale `cd <arch>` hints in the verify tools and the doc.odin paths updated. WASM stays at core/rexcode/wasm for now -- it is an IR, not an ISA, and will move under the forthcoming core:rexcode/ir once that layer lands. All 10 arches gen/builders/check/test green; import core:rexcode/isa/x86 verified working; wasm still compiles.
