* Add service manager infrastructure
The changes are (This will be a bit long):
- A ServiceManager class that spawns a background thread and deals with
service lifecycle management. The idea is that service lifecycle code
will run in async functions, so a single thread is enough to manage
any (reasonable) amount of services.
- A Service class, that offers start(), stop() and restart() methods
that simply notify the service manager to... well. Start, stop or
restart a service.
(!) Warning: Note that this differs from mp.Process.start/stop in that
the service commands are sent asynchronously and will complete
"eventually". This is good because it means that business logic is
fast when booting up and shutting down, but we need to make sure
that code does not rely on start() and stop() being instant
(Mainly pid assignments).
Subclasses of the Service class should use the on_start and on_stop
methods to monitor for service events. These will be run by the
service manager thread, so we need to be careful not to block
execution here. Standard async stuff.
(!) Note on service names: Service names should be unique within a
ServiceManager. Make sure that you pass the name you want to
super().__init__(name="...") if you plan to spawn multiple instances
of a service.
- A ServiceProcess class: A Service that wraps a multiprocessing.Process
into a Service. It offers a run() method subclasses can override and
can support in-place restarting using the service manager.
And finally, I lied a bit about this whole thing using a single thread.
I can't find any way to run python multiprocessing in async, so there is
a MultiprocessingWaiter thread that waits for multiprocessing events and
notifies any pending futures. This was uhhh... fun? No, not really.
But it works. Using this part of the code just involves calling the
provided wait method. See the implementation of ServiceProcess for more
details.
Mirror util.Process hooks onto service process
Remove Service.__name attribute
Do not serialize process object on ServiceProcess start.

* build with sqlite amalgamation
* non-platform specific
* use wget instead of curl
* remove unzip -d
* remove sqlite_vec from requirements and load the compiled version
* fix build
* avoid race in db connection
* add scale_factor and bias to description zscore normalization
* Added stop_event to util.Process
util.Process will take care of receiving signals when the stop_event is
accessed in the subclass. If it never is, SystemExit is raised instead.
This has the effect of still behaving like multiprocessing.Process when
stop_event is not accessed, while still allowing subclasses to not deal
with the hassle of setting it up.
* Give each util.Process their own logger
This will help to reduce boilerplate in subclasses.
* Give explicit types to util.Process.__init__
This gives better type hinting in the editor.
* Use util.Process facilities in AudioProcessor
Boilerplate begone!
* Removed pointless check in util.Process
The log_listener.queue should never be None, unless something has gone
extremely wrong in the log setup code. If we're that far gone, crashing
is better.
* Make sure faulthandler is enabled in all processes
This has no effect currently since we're using the fork start_method.
However, when we inevidably switch to forkserver (either by choice, or
by upgrading to python 3.14+) not having this makes for some really fun
failure modes :D
* Allow embedding of snapshot for description via config option
* docs
* frontend button
* Backend
* crop snapshot to region
* only show dropdown when event has snapshot
* fix cursor on dropdown
* crop on initial generation as well
* use enum for type
* fix type
* Subclass Process for audio_process
* Introduce custom mp.Process subclass
In preparation to switch the multiprocessing startup method away from
"fork", we cannot rely on os.fork cloning the log state at fork time.
Instead, we have to set up logging before we run the business logic of
each process.
* Make camera_metrics into a class
* Make ptz_metrics into a class
* Fixed PtzMotionEstimator.ptz_metrics type annotation
* Removed pointless variables
* Do not start audio processor when no audio cameras are configured
* Moved FrigateApp.init_config() into FrigateConfig.load()
* Move frigate config loading into main

* Register SIGTERM handler in main
* Ensure logging is setup during config parsing
* Removed pointless try

python's logging calls are not re-entrant, which caused at least one of
these to deadlock randomly.
* Reopen stdout/err on process fork
This helps avoid deadlocks (https://github.com/python/cpython/issues/91776).
