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.
