Initial: BESser umbrella for BES2600 driver mainlining

Sets up the BES2600 mainlining work tree with:

- README: project overview, hardware target, driver lineage
  (CW1200 -> Bestechnic -> arjan-vlek -> Mobian/danctnix), patch series
  status, repo map, build/deploy workflow.

- patches/: c1 patch generated by git format-patch from
  marfrit/bes2600-dkms branch bes2600/factory-request-firmware
  (checkpatch.pl --no-tree --strict: 0 errors / 0 warnings / 0 checks).

- scripts/: build-bes2600-on-ohm.sh, deploy-c1-to-ohm.sh,
  backup-ohm-kernel.sh - reproducible build + deploy + backup.

- fw-analysis/: per-blob strings.txt + fnnames.txt extracted from the
  4 firmware blobs pulled from ohm 2026-04-21. Source binaries NOT
  committed (Bestechnic-proprietary).

- notes/: observed-bugs.md (4 known bug surfaces with file:line +
  patch-series cross-reference), source-map.md (every public driver
  source variant + their canonical role).

Companion work tree: marfrit/bes2600-dkms (Mobian DKMS fork) at
git.reauktion.de.
