kernel/compressor_tree.cc, passes/tests/test_kogge_stone.cc,
passes/opt/peepopt_shiftpow2.pmg, and techlibs/lattice/lattice_dsp_nexus.pmg
(plus the 5 new constids it needs: A0, B0, PIPELINED, SIGNED, SUBTRACT)
were all added to main after the emil/twines-proc-srcloc fork point, so no
commit in this phase's range ever touches them. They still use the old
IdString-based addWire/addCell/setPort/getParam APIs (NEW_ID, plain \X
port names) that the twine migration replaces, so they fail to build
against current HEAD. Not attributable to any single commit in this
phase per task.md's carve-out for genuinely phase-spanning fixes -
bundled here as its own commit rather than folded into an unrelated
pick.
