The human-oriented plan output includes a short summary of the meaning of
all of the different "icons" used to describe different kinds of change,
but nothing was previously describing how OpenTofu uses "->" to describe
the transition between current and planned values for update in-place, "~".
We'll now include a concise note about that as part of the icon summary,
keeping things still relatively compact but nonetheless giving something
to refer to if a reader is unsure about the meaning of this notation.

The code for matching relevant_attributes against resource_drift entries
(a part of the heuristic for deciding whether to show "changes outside of
OpenTofu" in the human-oriented plan UI) was previously assuming that paths
in resource_drift would always be valid for the associated resource
instance object values because in most cases the language runtime will
detect invalid references and so fail to generate a plan at all.
However, when the reference is to something within a dynamically-typed
argument (such as the manifest in kubernetes_manifest) and when it appears
only as an argument to either the "try" or "can" functions (so the dynamic
error is intentionally suppressed) the language runtime can't catch it
and so the incorrect reference will leak out into relevant_attributes,
thereby violating assumptions made by the path matcher.
Instead then, we'll continue the existing precedent that this "relevant
attributes" mechanism is a best-effort heuristic that prefers to succeed
with an incomplete result rather than to fail, extending that to the
traversals in the plan renderer which will now treat incorrectly-typed
steps as not matching rather than causing OpenTofu to crash completely.
Since a reference to something that doesn't exist cannot succeed it also
cannot possibly _actually_ contribute directly to the final result of the
expression it appeared in, so in practice it should be okay to disregard
these invalid references for the purposes of deciding which changes outside
of OpenTofu seem likely to have caused the actions that OpenTofu is
proposing to make during the apply phase.

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.

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.
Resolves#2389

This commit replaces the existing jsonformat.PlanRendererOpt type with a new
type with identical semantics, located in the plans package.
We needed to be able to exchange the facts represented by
`jsonformat.PlanRendererOpt` across some package boundaries, but the jsonformat
package is implicated in too many dependency chains to be safe for that purpose!
So, we had to make a new one. The plans package seems safe to import from all
the places that must emit or accept this info, and already contains plans.Mode,
which is effectively a sibling of this type.
* command: keep our promises
* remove some nil config checks
Remove some of the safety checks that ensure plan nodes have config attached at the appropriate time.
* add GeneratedConfig to plan changes objects
Add a new GeneratedConfig field alongside Importing in plan changes.
* add config generation package
The genconfig package implements HCL config generation from provider state values.
Thanks to @mildwonkey whose implementation of terraform add is the basis for this package.
* generate config during plan
If a resource is being imported and does not already have config, attempt to generate that config during planning. The config is generated from the state as an HCL string, and then parsed back into an hcl.Body to attach to the plan graph node.
The generated config string is attached to the change emitted by the plan.
* complete config generation prototype, and add tests
* Plannable import: Add generated config to json and human-readable plan output
