.data now lives at the end of the dyn-path R+W PT_LOAD, just after .dynamic. The single segment covers .got.plt + .dynamic + .data; its filesz drops trailing zeros (BSS) while memsz spans the full extent. Relocation moves from main.c into each emit function so the static and dynamic paths use their own data_va — text→data refs land on the right VA regardless of path. Removes the early-error in dynout.c that previously refused any .data with -l/-L. Tests: 810_dyn gains two new dyn+.data fixtures (mutable read+write of an i32, plus a zero-init i64 verifying the BSS scan still produces a valid p_filesz<p_memsz under the shared segment).
