Change pack source: install all linux-firmware* packages in container and pack from /lib/firmware via [bash.rfs_common_install_all_alpine_firmware_packages()](scripts/rfs/common.sh:290) used by [bash.pack-firmware.sh](scripts/rfs/pack-firmware.sh:21). At runtime, overmount firmware flist on /lib/firmware by updating [sh.firmware.sh](config/zinit/init/firmware.sh:10). Update docs to reflect /lib/firmware mount and new pack strategy.

# Common helpers for RFS flist creation and manifest patching
|
|
# - No changes to existing build pipeline; this library is used by standalone scripts under scripts/rfs
|
|
# - Computes FULL_KERNEL_VERSION from configs (never uses uname -r)
|
|
# - Loads S3 (garage) config and builds rfs S3 store URI
|
|
# - Locates rfs binary and source trees for modules/firmware
|
|
# - Provides helper to patch .fl (sqlite) stores table to use HTTPS web endpoint
