- Removed inline Bullseye build recipe (moved to 'why not' appendix)
- Added build time estimates
- Cleaner table formatting
- gplan.so contents documented (cbang + camotics)

gplan.so: build from source using Raspbian Stretch Docker
...
Use balenalib/raspberry-pi-debian:stretch with legacy.raspbian.org repos.
Exact match: GCC 6.3, Python 3.5, GLIBC 2.24 — identical to the Pi.
First build ~25min (QEMU), subsequent builds ~1sec (cached image).
Replaces the broken Bullseye approach that had GLIBC/GLIBCXX mismatches.

Recommend using official release gplan.so instead.

Add cached gplan.so build: 30min first time, 3sec after
...
- Dockerfile.gplan: pre-built armv7 image with cbang + camotics objects
- build-gplan.sh: relinks against Python 3.5m in ~3sec
- Pi Python 3.5 headers cached in .pi/pi-python35.tar.gz (gitignored)
