fleet/ohm: pkgrel=6 reproducible from manifest (cumulative-pkgrel6-danctnix)

Replace the pkgrel=3-era cumulative-c5x-danctnix include with
cumulative-pkgrel6-danctnix — a single squashed diff representing
the bes2600 driver source state on ohm as of 2026-05-21.

Also drop:
- arch/arm64/scs-arm-neon-build-fix/ (removed in pkgrel=4)
- driver/bes2600/queue-pending-record-lock-bh-danctnix/ (in cumulative)
- driver/bes2600/tx-sdio-dma-oob-danctnix/ (in cumulative)
- driver/bes2600/join-confirm-reset-danctnix/ (in cumulative)

Resulting manifest: just two includes:
  driver/bes2600/cumulative-pkgrel6-danctnix/
  driver/bes2600/scan-filter-5ghz-danctnix/

Verified: ka-promote ohm produces a 136KB cumulative.patch that,
when applied to a fresh v7.0-danctnix1 staging tree, yields
drivers/staging/bes2600 source bit-identical to the pkgrel=6 build
on boltzmann. The only diff is build artifacts (.o, .cmd, .mod, etc.).

Kernel-agent can now generate the ohm-live source state without
reaching into the besser repository.

Closes ka#29 (per-series reconstruction tracking issue) by
delivering the deterministic-rebuild capability the original
per-series mirrors were meant to provide.

+## Why a cumulative
+
+These 22 commits are the converged per-series; while they exist as
+individual scope dirs in `marfrit/bes2600-dkms`, several have
+context-overlap rebase conflicts that make per-scope inclusion in
+kernel-agent fragile (cf. ka#29 / besser#22 reconstruction debacle).
+
+Shipping the cumulative as one file in kernel-agent guarantees the
+applied source state on `v7.0-danctnix1` is bit-identical to the
+pkgrel=6 build on ohm, without dragging the besser-repo branch state
+into kernel-agent's resolution path.
+
+## Apply order
+
+This patch is the **base** for the bes2600 driver scope. The remaining
+non-bes2600 patch (`scan-filter-5ghz-danctnix` for besser#1) layers on
+top via the apply order in `fleet/ohm.yaml`.
+
+## Provenance
+
+Generated by `git diff e0d752a..bes2600/join-confirm-failure-reset --
+bes2600/` against `marfrit/bes2600-dkms`, then path-rewritten
+`bes2600/` → `drivers/staging/bes2600/`. The baseline `e0d752a`
+corresponds to the v7.0-danctnix1 bes2600 staging tree.
