Return a custom error type from `VM.getCompileJob()`, so that underlying
errors can be wrapped and more info can be given to the caller. This
replaces a local logger call, preventing both the function and its
caller logging the same error.
Change the package base name of the Go code, from
`git.blender.org/flamenco` to `projects.blender.org/studio/flamenco`.
The old location, `git.blender.org`, has no longer been use since the
[migration to Gitea][1]. The new package names now reflect the actual
location where Flamenco is hosted.

As it was decided that the name "tags" would be better for the clarity
of the feature, all files and code named "cluster" or "worker cluster"
have been removed and replaced with "tag" and "worker tag". This is only
a name change, no other features were touched.
This addresses part of #104204.

As a note to anyone who already ran a pre-release version of Flamenco
and configured some worker clusters, with the help of an SQLite client
you can migrate the clusters to tags. First build Flamenco Manager and
start it, to create the new database schema. Then run these SQL queries
via an sqlite commandline client:
```sql
insert into worker_tags
(id, created_at, updated_at, uuid, name, description)
select id, created_at, updated_at, uuid, name, description
from worker_clusters;
insert into worker_tag_membership (worker_tag_id, worker_id)
select worker_cluster_id, worker_id from worker_cluster_membership;
```
If Shaman is used to submit the job files, store the job's checkout ID
(i.e. the path relative to the checkout root) in the database. This will
make it possible in the future to remove the Shaman checkout along with
the job itself.
The etag prevents job submissions with old settings, when the job
compiler script has been edited. The etag is the SHA1 hash of the
`JOB_TYPE` dictionary (as defined by the JavaScript file). The hash is
computed in a way that's independent of the exact formatting in the
JavaScript file. Also the actual JS code itself is irrelevant, just the
`JOB_TYPE` dictionary is used.
If there is a `scripts` directory next to the current executable, load
scripts from that directory as well.
It is still required to restart the Manager in order to pick up changes
to those scripts (including new/removed files), PLUS a refresh in the
add-on.
When on-disk job compiler scripts are supported, they will be reloaded
often, and it becomes more important to have the access to the map of
loaded job compilers thread-safe.
The global `scriptFS` variable was too easy to access, which caused an
issue where the mandatory `"scripts"` subdirectory was not passed.
Accessing via a getter function that hides this requirement prevents this.
Take some functions out of the `Service` struct, as they are more or less
standalone anyway. This will also make it easier later to make things
thread-safe, as that'll become important when files can get live-reloaded.
The `Load()` function returns a `*Service`, and it was confusing that the
local variable is named `compiler` instead. Now it's called `service`.
No functional changes.
Refactor the JS script file loading code so that it's tied to the `fs.FS`
interface for longer, and less to the specifics of our `embed.FS` instance.
This should make it possible to use other filesystems, like a real on-disk
one, to load scripts.
Add a small wrapper around github.com/google/uuid. That way it's clearer
which functionality is used by Flamenco, doesn't link most of the code to
any specific UUID library, and allows a bit of customisation.
The only customisation now is that Flamenco is a bit stricter in the
formats it accepts; only the `xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx` is
accepted. This makes things a little bit stricter, with the advantage
that we don't need to do any normalisation of received UUID strings.
The add-on code was copy-pasted from other addons and used the GPL v2
license, whereas by accident the LICENSE text file had the GNU "Affero" GPL
license v3 (instead of regular GPL v3).
This is now all streamlined, and all code is licensed as "GPL v3 or later".
Furthermore, the code comments just show a SPDX License Identifier
instead of an entire license block.
Each job compiler script now must define a `compileJob(job)` function,
which will be called by Flamenco when necessary.
This makes it possible to run the script without a job, and get other
exported symbols from it, such as metadata about which settings its job
type needs/exposes.
