* fix(state): prefetch shared remote charts instead of serializing sync/diff (#2741) PR #2662 fixed a Windows chart-download race (#768) by wrapping the entire helm upgrade/diff operation in a per-chart+version lock, not just the download. Since sync/apply/diff never set ForceDownload, releases sharing a remote chart end up fully serialized even at high --concurrency. Add ChartPrepareOptions.PrefetchSharedRemoteCharts: PrepareCharts groups selected releases by chart+version, and force-downloads (once) any chart used by 2+ releases that also resolve to identical acquisition flags (--verify/--keyring/--plain-http/--insecure-skip-tls-verify/--devel) and to a configured repository (or OCI ref) - not a bare \"dir/chart\"-shaped local path. That materializes release.ChartPath, which lets withChartOperationLock's existing ChartPath != \"\" guard skip the lock, restoring concurrency without touching the #768 protection for charts that aren't prefetched. Also add chartFetchFlags to give forcedDownloadChart's \`helm fetch\` the same verify/keyring/TLS flags flagsForUpgrade already applies, closing a parity gap that predates this change (affects lint/unittest/pull too).

Helm's VerifyChart only accepts a packaged .tgz/provenance pair, not an unpacked directory, so upgrading a prefetched chart with verify enabled would fail. Exclude --verify from prefetch eligibility entirely rather than trying to suppress the later flag - those releases just keep the pre-existing serialized-lock behavior, unaffected by this feature. 2. The per-key flag-agreement signature joined flags with a space, which isn't injective: a keyring path containing a space and a flag-like token could collide with a different keyring plus a real flag, silently deduplicating releases with different acquisition settings. Join with NUL instead, which can't appear in an OS argument.

Apply the override once upfront, before the grouping loop reads release.Chart.
