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.

Continuing our work to gradually plumb context.Context to everywhere that
we want to generate OpenTelemetry traces, this completes the call path
for most (but not all) of the gRPC requests to provider plugins, so that
we can add OpenTelemetry trace instrumentation in a future commit.
Unfortunately there are still a few providers.Interface callers left in
functions that don't have context.Context plumbed to them yet, and so
those are temporarily stubbed as context.TODO() here so we can more easily
find and complete them later.
The two gRPC implementations of providers.Interface were previously making
provider requests using a single context.Context established at the time
the provider process was started, but that isn't an appropriate context
to use for per-request concerns like tracing, so that context is now
unused and could potentially be removed in a future commit, but this change
already got pretty large and so I intend to deal with that separately
later.
This now exposes the gRPC provider calls to potential context cancellation
that they would previously observe only indirectly though the Stop method.
Since Stop is primarily used for graceful shutdown of ApplyResourceChange,
the changes here explicitly disconnect the cancellation signal for
ApplyResourceChange in particular, while letting the others get canceled
in the normal way since they are expected to be free of significant
side-effects. In future work we could consider removing Stop from the
internal API entirely and keeping it only as an implementation detail of
the gRPC implementation of this interface, with ApplyResourceChange
directly reacting to context cancellation and sending the gRPC Stop call
itself, but again that's too much change for this already-large commit.
The internal/legacy package currently contains some legacy code preserved
for the benefit of the backends, and unfortunately contains more than is
strictly necessary to support those callers, and so there was some dead
code there that also needed updating. provider_mock.go is removed entirely
because it's just an older copy of the similar file in package tofu. The
few calls to providers in schemas.go are updated to use
context.Background() rather than context.TODO() because we have no
intention of plumbing context.Context into that legacy code, and will
hopefully just delete it wholesale one day.

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.

Go 1.24 introduces stricter checks for format string validation.
This commit fixes instances where non-constant format strings were
used in calls to functions like `fmt.Errorf`, `fmt.Printf`, and similar.
Changes include:
- Replacing dynamically constructed strings passed as format strings
with constant format strings.
- Refactoring `fmt.Sprintf` calls to ensure the format string matches
the number of arguments provided.
- Simplifying redundant formatting and ensuring compliance with Go
1.24's stricter `vet` tool checks.
This update ensures compatibility with Go 1.24 and prevents potential
runtime errors caused by misinterpreted dynamic format strings.

This function was previously quite long and complex, so this commit splits
it into a number of smaller functions.
The previous code structure was made more awkward by having to work around
all being together in one function -- particularly the part iterating over
the values used in an expression -- and so the new layout is quite
different and thus the diff is hard to read. However, there are
intentionally no test changes in this commit to help us be confident that
this has not regressed anything, and the existing unit tests for this
component seem quite comprehensive.

We're intending to gradually improve all of the existing functions that
fail these checks as a separate project from other work, because fixing
for these particular lint rules tends to be too invasive to be safe or
sensible to combine with other work.
Therefore we'll temporarily disable these lints from the main lint run
and add a separate .golangci-complexity.yml that we can use to track our
progress towards eliminating those lint failures without continuing to
litter the code with nolint comments in the meantime.
This also removes all of the existing nolint comments for these linters so
that we can start fresh and review each one as part of our improvement
project.
We'll re-enable these linters (and remove .golangci-complexity.yml) once
each example has either been rewritten to pass the checks or we've
concluded that further decomposition would hurt readability and so added
"nolint" comments back in so we can review whether our lint rules are too
strict once we've got a bunch of examples to consider together.
