Fixes#1920
Installer-written exact versions (e.g., oh-my-opencode@3.5.2) were incorrectly treated as user-pinned, blocking auto-updates for all installer users.
Fix isPinned to only block auto-update when pinnedVersion is an explicit semver string (user's intent). Channel tags (latest, beta, next) and bare package name all allow auto-update.
Fix installer fallback to return bare PACKAGE_NAME for stable versions and PACKAGE_NAME@{channel} for prerelease versions, preserving channel tracking.
When a user pins oh-my-opencode to a specific version (e.g., oh-my-opencode@3.4.0),
the auto-update checker now respects that choice and only shows a notification toast
instead of overwriting the pinned version with latest.
- Skip updatePinnedVersion() when pluginInfo.isPinned is true
- Show update-available toast only (notification, no modification)
- Added comprehensive tests for pinned/unpinned/autoUpdate scenarios
Fixes#1745
When bun install fails after updating the config pin, the config now shows the
new version but the actual package is the old one. Add revertPinnedVersion() to
roll back the config entry on install failure, keeping config and installed
version in sync.
