Phase 0 batch 2. Sites: w6a/parse.ww (asym, aprog, aoperand ×2), w6l/main.ww (lnk), w6l/obj.ww (defent, armember, lobj, lrel ×2). obj.ww's hdrsize *u8 buffer at line 344 + 7 other runtime-N byte buffers across the three files (path bufs, n+1 cstr copies, cap realloc) stay deferred to #8. Verified via 991_w6a_ww + 992_w6l_ww + 995_self_rebuild + 996_dyn_ww byte-identity. make test 132/132.
