* fix: route registry messages to stderr in template and show
When pulling an OCI chart, the registry client prints "Pulled: ..." and
"Digest: ..." status lines (and deprecation/underscore warnings) to its
configured output writer. Since v4.2.1 (introduced by #32056), these
messages leaked into the stdout output of helm template and helm show,
breaking downstream consumers such as cdk8s and other YAML parsers.
Fix by passing the command's stderr to the registry client in the
template and show commands instead of stdout. This keeps stdout clean
for machine-readable YAML while still surfacing registry warnings and
status messages on stderr for troubleshooting, rather than discarding
them. The pull/push commands continue to print these messages on their
normal output writer.
The show command's addRegistryClient writer parameter is renamed to
registryOut and wired through to the registry client, so it is no longer
a no-op.
Fixes#32215

* refactor: remove per-file decompression size limit
Remove MaxDecompressedFileSize as it's no longer necessary after
migrating to a maintained JSON schema library (santhosh-tekuri/jsonschema/v6).
The original limit was added to protect against vulnerabilities in an
unmaintained library.
The total decompressed chart size limit (MaxDecompressedChartSize) remains
to protect against other attack vectors.

* fix: enforce aggregate size budget on directory loading
Directory-based chart loading (`LoadDir`) used unbounded `os.ReadFile`
calls with no total size check. Archive loading already enforces
`MaxDecompressedChartSize` via a remaining-byte budget but directory
loading did not, leaving local charts and `file://` dependencies as
an unbounded memory path.
Add `ReadFileWithBudget` in the archive package and use it in both
v2 and v3 directory loaders so they track the same aggregate budget.

* fix: cap directory budget reads with LimitReader
Use `os.Open` + `io.LimitReader` instead of `os.ReadFile` in
`ReadFileWithBudget` so a file that grows between stat and read
cannot allocate unbounded memory.
Also fix `MaxDecompressedFileSize` doc comment to reflect it is
unused/deprecated, add nil guard on remaining, and check
`os.Stat` errors in tests.

* fix(provenance): support GnuPG keybox (pubring.kbx) keyrings
Starting with GnuPG 2.1, file-backed public keyrings can use
~/.gnupg/pubring.kbx instead of the legacy pubring.gpg. Helm only read
the legacy format, so chart and plugin verification failed on
installations using the file-backed keybox.
Make the keyring loader format-aware:
- GnuPG keybox (pubring.kbx): extract OpenPGP keyblocks from the
keybox container without adding a dependency. Skip ephemeral blobs,
matching GnuPG's own read behavior.
- ASCII-armored keyrings: load single or concatenated exports.
- Legacy binary packet streams (pubring.gpg): retain the existing path.
defaultKeyring() falls back to pubring.kbx when pubring.gpg is absent.
pubring.gpg keeps precedence when both files exist.
This change covers file-backed public keyrings. It does not read the
SQLite database used by keyboxd, which needs a separate design.

* fix(provenance): treat only not-exist as keyring absence in defaultKeyring
A stat error other than 'not exist' (e.g. a permission problem) meant
the file may well be present, but defaultKeyring() skipped past it: an
unreadable pubring.gpg silently lost precedence to pubring.kbx, and the
surfaced error could point at the wrong file. Treat only fs.ErrNotExist
as absence. For any other stat error, return that path unchanged so the
real error surfaces when the keyring is opened.

TestInstallRelease_Wait_Interrupted and
TestInstallRelease_RollbackOnFailure_Interrupted assert that the detached
installation goroutine has exited by sleeping a fixed 10s -- exactly the
FailingKubeClient WaitDuration the goroutine blocks on. Sleeping the same
duration the goroutine takes is a zero-margin race: if the goroutine
finishes a hair after the fixed sleep elapses (scheduler jitter under load),
getGoroutineCount() has not decremented yet and the assertion flakes.
Replace the fixed sleep + point-in-time assert with is.Eventually polling
getGoroutineCount() (30s ceiling, 10ms tick). It returns as soon as the
goroutine has actually finished and no longer races the exact wait
duration. Test-only; no change to install behavior.

Closes#32396.
StampModTimes now normalizes the supplied time to UTC and truncates to
whole seconds before stamping. Without this, an SDK caller passing a
local-timezone or sub-second time.Time would produce a Chart.lock
generated: field with a timezone offset or fractional seconds, making
the lock file content non-reproducible across machines even when the
same SOURCE_DATE_EPOCH value is used — defeating the purpose of the
feature.
Also add:
- testdata/charts/chart-with-lock fixture: a minimal chart with a
Chart.lock whose generated: timestamp predates SOURCE_DATE_EPOCH.
- TestRunWithSourceDateEpochStampsLockGenerated: packages the fixture
with SourceDateEpoch set to a non-UTC, sub-second time.Time and
asserts that the resulting archive's Chart.lock entry has both the
correct tar modtime and the correct (normalized) generated: value in
the marshaled YAML.

Add a new --description flag to the helm rollback command that allows
users to specify a custom description explaining why the rollback was
performed. This description is stored in the release metadata.
Changes:
- Add Description field to the Rollback action struct
- Add --description flag to the rollback CLI command
- Add 512 character limit validation for the description
- Default to 'Rollback to <version>' when no description is provided
The description flag is optional and follows the same pattern used by
the install and upgrade commands.
