# Description
This PR introduces `ProgramInfo` to replace the old `ProgInfo` and
consistently use it where we require plugin, install dependencies and
initialize language runtimes.
## Checklist

<!--
If the change(s) in this PR is a modification of an existing call to the
Pulumi Cloud,
then the service should honor older versions of the CLI where this
change would not exist.
You must then bump the API version in
/pkg/backend/httpstate/client/api.go, as well as add
it to the service.

- [ ] Yes, there are changes in this PR that warrants bumping the Pulumi
Cloud API version
<!-- @Pulumi employees: If yes, you must submit corresponding changes in
the service repo. -->
Per team discussion, switching to gofumpt.
[gofumpt][1] is an alternative, stricter alternative to gofmt.
It addresses other stylistic concerns that gofmt doesn't yet cover.

See the full list of [Added rules][2], but it includes:
- Dropping empty lines around function bodies
- Dropping unnecessary variable grouping when there's only one variable
- Ensuring an empty line between multi-line functions
- simplification (`-s` in gofmt) is always enabled
- Ensuring multi-line function signatures end with
`) {` on a separate line.

gofumpt is stricter, but there's no lock-in.
All gofumpt output is valid gofmt output,
so if we decide we don't like it, it's easy to switch back
without any code changes.
gofumpt support is built into the tooling we use for development
so this won't change development workflows.
- golangci-lint includes a gofumpt check (enabled in this PR)
- gopls, the LSP for Go, includes a gofumpt option
(see [installation instrutions][3])

This change was generated by running:
```bash
gofumpt -w $(rg --files -g '*.go' | rg -v testdata | rg -v compilation_error)
```
The following files were manually tweaked afterwards:
- pkg/cmd/pulumi/stack_change_secrets_provider.go:
one of the lines overflowed and had comments in an inconvenient place
- pkg/cmd/pulumi/destroy.go:
`var x T = y` where `T` wasn't necessary
- pkg/cmd/pulumi/policy_new.go:
long line because of error message
- pkg/backend/snapshot_test.go:
long line trying to assign three variables in the same assignment
I have included mention of gofumpt in the CONTRIBUTING.md.
grpc.WithInsecure is deprecated [1].
Instead, we're expected to use:
grpc.WithTransportCredentials(insecure.NewCredentials())
This updates all instances across pkg/, sdk/ and tests/.

In service to #11808
This allows the pulumi-language-go plugin to start up providers directly
from .go source files.
The other language providers will be extended to support this as well in
time.
* Revise host mode.
The current implementation of host mode uses a `pulumi host` command and
an ad-hoc communication protocol between the engine and client to
connect a language host after the host has begun listening. The most
significant disadvantages of this approach are the communication
protocol (which currently requires the use of stdout), the host-specific
command, and the difficulty of accommodating the typical program-bound
lifetime for an update.
These changes reimplement host mode by adding engine support for
connecting to an existing language runtime service rather than launching
a plugin. This capability is provided via an engine-specific language
runtime, `client`, which accepts the address of the existing languge
runtime service as a runtime option. The CLI exposes this runtime via
the `--client` flag to the `up` and `preview` commands, which similarly
accepts the address of an existing language runtime service as an
argument. These changes also adjust the automation API to consume the
new host mode implementation.
