Subject: [PATCH] Add all PDKs and export variables.yaml in Bazel build
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add orfs_pdk definitions for gf180, ihp-sg13g2, nangate45, and
sky130hs.  These platform directories already exist but were not
exposed to Bazel consumers (only asap7 and sky130hd were defined).

Also:
- Export scripts/variables.yaml for external variable metadata access
- Add synth*.v to makefile_yosys glob (picks up synth_wrap_operators-booth.v)
- Add lyp, cfg, json, layermap, lyt_generic extensions per PDK
- Separate lib/lib.gz into libs attribute (gf180 has only .lib.gz)
