forgectrl: promote to its own repo, recipe fetches the pinned git source

Sources live at github.com/ScottW514/forgectrl (history extracted, layout src/ + init/); the recipe pins SRCREV and installs the init script from the repo. Adds the build-forgectrl.sh bench cross-compile script.

 | `flow_recheck_char.py` | Characterizes short in-run re-checks and the differential metric; shows why over-temp cannot see a stopped pump and why passive warming trends are ambiguous. |
 | `temp_calibrate.py` | Coolant temperature spot-check helper (`watch` / `point <measured_C>` / `fit`) — pairs a measured temperature with averaged raw ADC readings and fits a per-machine line to sanity-check the factory curve against a thermometer. |
 | `build-glowforge.sh` | Cross-compiles **grblHAL-glowforge** (the canonical driver repo, `../../../grblHAL-glowforge`) in the forge-yocto WSL distro. Run: `wsl -d forge-yocto -- bash <path>/build-glowforge.sh` (from PowerShell; Git Bash mangles /mnt/c paths). This is the production controller build. |
+| `build-forgectrl.sh` | Cross-compiles **forgectrl** (the canonical control-daemon repo, `../../../forgectrl`) the same way, borrowing the toolchain from the forgectrl recipe workdir (regenerate with `bitbake forgectrl` after a clean). |
 | `build-feeder.sh` | Cross-compiles `feeder.c` the same way. |
 | `puls_profile.py` | Decodes factory `.puls` streams (raw or GF1-headered) into velocity/accel profiles: peak speeds, ramp-slope fits, per-move segments, Z cadence. Runs anywhere (stdlib only). Source of the factory-true grblHAL defaults: 700/590 mm/s² accel, 200 mm/s max rate, 28160 Hz travel tick. |
 | `bench_m2.py` | Motion-quality bench, runs against the board over TCP:23: bounded round-trip jogs (sanity, max-rate, diagonal) + feed-hold/resume mid-move, reporting peak feed, state transitions, and position drift. |
