Previously the Go toolchain had no explicit support for "tools" and so we
used the typical Go community workaround of adding "tools.go" files (two,
for some reason) that existed only to trick the Go toolchain into
considering the tools as dependencies we could track in go.mod.
Go 1.24 introduced explicit support for tracking tools as part of go.mod,
and the ability to run those using "go tool" instead of "go run", and so
this commit switches us over to using that strategy for everything we were
previously managing in tools.go.
There are some intentional exceptions here:
- The protobuf-compile script can't use "go tool" or "go run" because the
tools in question are run only indirectly through protoc. However, we
do still use the "tool" directive in go.mod to tell the Go toolchain that
we depend on those tools, so that it'll track which versions we are
currently using as part of go.mod.
- Our golangci-lint Makefile target uses "go run" to run a specific
version of golangci-lint. We _intentionally_ don't consider that tool
to be a direct dependency of OpenTofu because it has a lot of indirect
dependencies that would pollute our go.mod file. Therefore that continues
to use "go run" after this commit.
- Both of our tools.go files previously referred to
github.com/nishanths/exhaustive , but nothing actually appears to be
using that tool in the current OpenTofu tree, so it's no longer a
dependency after this commit.
All of the dependencies we have _only_ for tools are now classified as
"indirect" in the go.mod file. This is the default behavior of the Go
toolchain and appears to be motivated by making it clearer that these
modules do not contribute anything to the runtime behavior of OpenTofu.
This also corrected a historical oddity in our go.mod where for some reason
the "indirect" dependencies had been split across two different "require"
directives; they are now all grouped together in a single directive.

We previously added the -config mode for showing the entire assembled
configuration tree, including the content of any descendent modules, but
that mode requires first running "tofu init" to install all of the
provider and module dependencies of the configuration.
This new -module=DIR mode returns a subset of the same JSON representation
for only a single module that can be generated without first installing
any dependencies, making this mode more appropriate for situations like
generating documentation for a single module when importing it into the
OpenTofu Registry. The registry generation process does not want to endure
the overhead of installing other providers and modules when all it actually
needs is metadata about the top-level declarations in the module.
To minimize the risk to the already-working full-config JSON representation
while still reusing most of its code, the implementation details of package
jsonconfig are a little awkward here. Since this code changes relatively
infrequently and is implementing an external interface subject to
compatibility constraints, and since this new behavior is relatively
marginal and intended primarily for our own OpenTofu Registry purposes,
this is a pragmatic tradeoff that is hopefully compensated for well enough
by the code comments that aim to explain what's going on for the benefit
of future maintainers. If we _do_ find ourselves making substantial changes
to this code at a later date then we can consider a more significant
restructure of the code at that point; the weird stuff is intentionally
encapsulated inside package jsonconfig so it can change later without
changing any callers.

The "tofu show" command has historically been difficult to extend to meet
new use-cases, such as showing the current configuration without creating
a plan, because it was designed to take zero or one arguments and then try
to guess what the one specified argument was intended to mean.
This commit introduces a new style where the type of object to inspect is
specified using command line option syntax, using one of two
mutually-exclusive options:
-state Show the latest state snapshot.
-plan=FILE Show the plan from the given saved plan file.
We expect that a future commit will extend this with a new "-config" option
to inspect the configuration rooted in the current working directory, and
possibly with "-module=DIR" to shallowly inspect a single module without
necessarily having to fully initialize it with all of its dependencies
first. However, both of those use-cases (and any others) are not in scope
for this commit, which is focused only on refactoring to make those future
use-cases possible.
The old mode of specifying neither option and providing zero or one
positional arguments is still supported for backward compatibility.
Notably, the legacy style is the only way to access the legacy behavior of
inspecting a specific state snapshot file from the local filesystem, which
has not often been used since Terraform v0.9 as we've moved away
from manual management of state files to the structure of state backends.
Those who _do_ still need that old behavior can still access it in the
old way, but there will be no new-style equivalent of it unless we learn
of a compelling use case for it.
