--- Read ELF symbol addresses by walking the `.symtab` + `.strtab` sections directly (no `nm` subprocess).
--- Returns a map `{name -> {addr, size_bytes}}` for every `code_<name>` symbol.
--- Returns a map `{name -> {addr, size_bytes}}` for every defined symbol.
---
--- **Conventions:**
--- - ELF32 symtab entry = 16 bytes (`st_name:4 + st_value:4 + st_size:4 + st_info:1 + st_other:1 + st_shndx:2`); offsets within each entry are zero-based wire offsets.
--- - Direct Lua `string.byte`/`string.sub`/`string.find` boundaries receive `+ 1`.
--- - We filter on STB_GLOBAL (high nibble of st_info = 1) to match `nm`'s default (external symbols only). STB_WEAK excluded.
--- - The `code_` prefix is stripped (MipsAtom_ macros emit bare atom names, no `code_` prefix).
--- - Keys are the ELF symbol names as written (the C ident).
--- - `st_size > 0` filter excludes undefined/imported symbols.
