treewide: reword lime_release and extend the usage of libremesh.mk

[a-gave]

hotplug-initd-services: create empty folder during package install
  The empty directory is created now during the package's install phase
  by the buildroot or the imagebuilder.
  Added it also to the package's conffiles to leave a trace of that
  for apk when it is ran from inside the device
  /etc/hotplug.d/initd/
libremesh.mk: extend the usage to all packages without a pkg_source_url
lime-apply: do not run hooks if there aren't any
  i.e. if lime-app is not installed
lime-debug: use libremesh.mk
lime-docs: fix banner not displayed
lime-system: use libremesh.mk to remove comments from the built package
lime-system: drop compatibility script for v2020.4 migrate-wifi-bands
lime-system: reword /etc/lime_release 'development' to 'nightly'
  which is shorter and emphasizes the fact that the code is usable but it
  is not a fixed/stable release. While 'development' is more vague.
lime-system: reword lime_description and add it to /usr/lib/os-release
  from: LiMe master development (master rev. 0b6b5c5 20260810_1130)
  to:   LibreMesh 25.12.5 r26.222.40775~0b6b5c5 nightly
  This text then displayed:
  - in the lime-app status page
  - via ssh after the banner via the profile.d/10-lime-banner.sh
  - via cli running `ubus call system board`
lime-system: move the uci-defaults 89_lime-release execution to Makefile
lime-system: create empty folders during package install
  The empty directories are created now during the package's install phase
  by the buildroot or the imagebuilder.
  Added them also to the package's conffiles to leave a trace of that
  for apk when it is ran from inside the device.
  /etc/hotplug.d/lime-apply/
  /etc/hotplug.d/lime-config/
  /etc/lime-assets/community/
  /etc/lime-assets/node/
lime-system: prevent duplicated code for coloured prompt across sysupgrades
scripts: add release.sh
shared-state-async: symlink script and add the missing dependency on
  shared-state

Fixes: #766

Edited the description to mention the removal of comments from the package lime-system using libremesh.mk

[ilario]

here it seems that the expression uses a "," as a field separator, but then changes to "/", no?

Thanks fixed in e1c5e31 https://github.com/libremesh/lime-packages/compare/783a7bf374899917371c7a8a98f4ed8e589bab5a..e1c5e310b8483bbd9835e3df1d73df2d9b1b04dc

Aren't the new .placeholder files you introduced in this pull request enough for ensuring that these folders are created?

[a-gave]

The /etc/lime-assets/{community,node}/.placeholder is deleted as well as the whole /etc/lime-assets/.
It is created instead in the same way as the directory /etc/hotplug.d/lime-config/ during the package install phase, so by apk. It is indeed just to uniform the way lime-system creates the three empty directories.

[ilario]

I don't understand, but it is ok :)

[ilario]

This is great!
Finally we are using the libremesh.mk file for every Makefile :D
Tested and it seems good to me and ready to merge, thanks!
Merge when you consider to.

lime-system: prevent duplicated code for coloured prompt across sysupgrades

Tested on QEMU and now seems ready to go

[a-gave]

The lime-system post-install script was executing only during image creation.
Removed in the last commit the check for IPKG_INSTROOT to let it run also when installing lime-system from apk from a plain openwrt

Retested on qemu

[a-gave]

Added a minor/trivial change to run hooks from lime-apply inside an 'sh -c'
from:

ACTION=$action "$file" >/dev/null

to

sh -c "ACTION=$action $file" >/dev/null
