Refactor sync mgr

[dmartinol]

Fixes: #42

• Added missing config options in Config struct
• Moved sync code from toolhive repo and adapted to not use MCPRegistry for config and status data
  • Adapted tests for the same reason
• Added status package with initial definition of status data (probably needs to be reviewed)
• Adapted repo layout to recent changes

Looks good to me, but please wait for approval from @rdimitrov, @jhrozek, or @ChrisJBurns who should have more context.

My only concern is the extensive usage of *config.Config, which should probably be an interface, an accessor, or certain config fields instead. But this can be refactored and cleaned up later.
