Use theme config templates with singular color definition (#4053)

* Attempt to templaterize the theme specific files

* Cleanup

* Slim down

* Combine render into -set

* Pull out the dynamic template rendering again, but simpler

* Fix vars

* Variables are lowercase

* Better presentation

* Fix missing colors

* Provide stripped values too

* Fix colors for regular hex format

* Bring back explicit btop themes

They're too involved to derive from a basic color set

* Make an atomic swap of the theme directories

* No longer used by walker to cancel

* Explain why

* Remove redundant const

* Consistent const naming

* No longe have $THEMES_DIR

* Correct the blue

* Set opencode colors too

* Fix colors for readability

* Move the templates together with the others in default

* Split user themes and default themes

* Fix paths

* Look for both user themes and default themes

Plus speed things up

* Migrate to the new setup where default themes live inside omarchy

* Explicitly store the name of the current theme

* Cleanup

* No longer need omarchy-theme-next since themes are now fully rendered, not symlinks

* Get current theme name from the new theme.name file

* Look for user background images in dedicated directory

* Need yq for toml

* Need yq to parse colors.toml

* Look for backgrounds matching the new theme.name

We no longer have symlinks

* Migrate existing user backgrounds to the new proper location

* Install user backgrounds in the correct path

* Fix quoting

* Just rely on the system theme for opencode and get ready for USRSIG2 being available to live reload

* Fix template generation for rgb colors
