* 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 `AgentConn` to `WorkspaceAgentConn`
The codersdk was becoming bloated with consts for the workspace
agent that made no sense to a reader. `Tailnet*` is an example
of these consts.
* chore: remove `Get` prefix from *Client functions
* chore: remove `BypassRatelimits` option in `codersdk.Client`
It feels wrong to have this as a direct option because it's so infrequently
needed by API callers. It's better to directly modify headers in the two
places that we actually use it.
* Merge `appearance.go` and `buildinfo.go` into `deployment.go`
* Merge `experiments.go` and `features.go` into `deployment.go`
* Fix `make gen` referencing old type names
* Merge `error.go` into `client.go`
`codersdk.Response` lived in `error.go`, which is wrong.
* chore: refactor workspace agent functions into agentsdk
It was odd conflating the codersdk that clients should use
with functions that only the agent should use. This separates
them into two SDKs that are closely coupled, but separate.
* Merge `insights.go` into `deployment.go`
* Merge `organizationmember.go` into `organizations.go`
* Merge `quota.go` into `workspaces.go`
* Rename `sse.go` to `serversentevents.go`
* Rename `codersdk.WorkspaceAppHostResponse` to `codersdk.AppHostResponse`
* Format `.vscode/settings.json`
* Fix outdated naming in `api.ts`
* Fix app host response
* Fix unsupported type
* Fix imported type
