Fix ASan leak in corpus token_map and Windows/Linux vector blob assembly

- semantic.c: free strdup'd keys+values in token_map via cbm_ht_foreach
  before cbm_ht_free (44KB leak in 7920 allocations)
- code_vectors_blob.S: add Windows COFF branch (.rdata,"dr") alongside
  macOS Mach-O and Linux ELF sections
