* chore: add /v2 to import module path
go mod requires semantic versioning with versions greater than 1.x
This was a mechanical update by running:
```
go install github.com/marwan-at-work/mod/cmd/mod@latest
mod upgrade
```
Migrate generated files to import /v2
* Fix gen
* chore: rename startup logs to agent logs
This also adds a `source` property to every agent log. It
should allow us to group logs and display them nicer in
the UI as they stream in.
* Fix migration order
* Fix naming
* Rename the frontend
* Fix tests
* Fix down migration
* Match enums for workspace agent logs
* Fix inserting log source
* Fix migration order
* Fix logs tests
* Fix psql insert
This commit adds two new `agentsdk` functions, `StartupLogsSender` and
`StartupLogsWriter` that can be used by any client looking to send
startup logs to coderd.
We also refactor the `agent` to use these new functions.
As a bonus, agent startup logs are separated into "info" and "error"
levels to separate stdout and stderr.
