* feat: honor SOURCE_DATE_EPOCH for chart archives
Add StampModTimes() on Chart struct to recursively set ModTime on
all chart file entries. CLI reads SOURCE_DATE_EPOCH env var and wires
through all 5 commands: package, install, upgrade, dep build, dep update.
Removes unused v3 duplicate source_date_epoch.go (YAGNI).
Inlines env var parsing to CLI layer from chart util.

* docs: document SOURCE_DATE_EPOCH in environment variables help
Add a short entry for $SOURCE_DATE_EPOCH to the env var table shown
in 'helm help'. The variable is honored by 'helm package', 'install',
'upgrade', 'dep build', and 'dep update' to produce reproducible chart
archives. Full documentation belongs in helm-www.

* fix: adapt SourceDateEpoch to upstream refactored dep check
Upstream/main restructured the dependency error handling in install.go
and upgrade.go from a nested-if block (if DependencyUpdate) to an
early-return pattern (if !DependencyUpdate). Adapt the feature's
Manager construction to match the new code structure.

When multiple processes try to download the same chart version
concurrently (e.g., via Terraform), they can race to write the
destination file. On Windows, this results in 'Access Denied'
errors because the file cannot be renamed while another process
has a handle to the destination.
This commit introduces 'PlatformAtomicWriteFile' to the fileutil
package. On Unix-like systems, it simply delegates to AtomicWriteFile,
maintaining existing behavior. On Windows, it coordinates writes using
a lock file (.lock). It acquires the lock, then performs the atomic
write.
Crucially, this implementation ensures that existing files are
overwritten (rather than skipped). This ensures that if a chart is
republished with the same version, the local cache is correctly updated,
preventing stale data issues.

The repo package is internally versioned at v1. Repos were designed
to be versioned. This change moves it to a versioned directory the
same way other packages are now being handled.

A few things are added here:
1. The cache is made to be more generic as a content based cache.
It could be used for other things such as plugins
2. Flags were added to specify the content cache locaiton rather
than rely on the repository cache. Keeping the 2 the same
hid bugs and errors.
3. Tests were added and updated to ensure the cache is used and
tested

The previous cache was based on chart name and version. If 2 charts
with different content had the same name and version they would collide.
Helm did not trust the cache because of this and always downloaded
content. It was a short lived cache.
This commit introduces a content based cache which is based on the
content rather than file name. Charts with the same name but different
content are no longer an issue.
While the system assumes a file based interface, the cache system
is pluggable. In the future, it should return bytes for the content
instead of paths to it. That would requie a larger change for Helm 5
or later.

The test was failing intermittently because Go's map iteration order
is randomized (see `range repos` in `findChartUrl`).
When looking up the `baz` chart with repository URL http://example.com/helm,
two repositories match due to trailing slash equivalence:
- testing-relative (URL: http://example.com/helm) - contains baz chart GOOD
- testing-relative-trailing-slash (URL: http://example.com/helm/) - does not contain baz chart.. NOT GOOD
The urlutil.Equal() function treats these URLs as equivalent, but
depending on which repository the random map iterator encounters
first, the test would either pass or fail with "entry not found".
So I changed the third test case from baz to foo chart, since foo exists
in both matching repositories. This eliminates the race condition while
preserving all test expectations and logic.
`findChartURL()` iterates over a map without deterministic
ordering, causing the first-match-wins behavior to be non-deterministic
when multiple repositories match the same URL pattern.
