[Bug]: Installer-pinned versions are treated as user-pinned, preventing auto-update for all installer users

• I have read the documentation or asked an AI coding agent with this project's GitHub URL loaded and couldn't find the answer

Bug Description

After the #1745 fix (shipped in v3.5.2), the auto-updater treats all exact-versioned plugin entries as "user-pinned" and skips auto-update. Since the installer (bunx oh-my-opencode install) always writes an exact version (e.g., oh-my-opencode@3.5.2), every user who installed via the official installer is stuck on their install-time version with no auto-update.

The core issue is that isPinned in plugin-entry.ts cannot distinguish between:

• Installer-pinned: addPluginToOpenCodeConfig(version) writes oh-my-opencode@3.5.2 automatically
• User-pinned: user manually edits opencode.json to lock a specific version

Both produce the same format (oh-my-opencode@X.Y.Z), so the auto-updater skips both.

Steps to Reproduce

1. Install oh-my-opencode via bunx oh-my-opencode install (writes oh-my-opencode@3.5.2 to opencode.json)
2. New version is released (e.g., 3.7.1)
3. Restart opencode — toast shows "v3.7.1 available. Restart to apply."
4. Restart opencode again — same toast, version still 3.5.2
5. Check ~/.cache/opencode/package.json — still "oh-my-opencode": "3.5.2", confirming bun install was never triggered

Expected Behavior

Users who installed via the official installer should receive auto-updates. Only users who manually edit opencode.json to pin a specific version should be excluded from auto-update.

Actual Behavior

The auto-updater detects the update, shows a toast notification ("Restart to apply"), but never actually updates the config or runs bun install. Restarting has no effect. The relevant code path:

// background-update-check.ts
if (pluginInfo.isPinned) {
  await showUpdateAvailableToast(ctx, latestVersion, getToastMessage)
  log(`User-pinned version detected (${pluginInfo.entry}), skipping auto-update.`)
  return  // exits without calling updatePinnedVersion() or bun install
}

// plugin-entry.ts
const isPinned = pinnedVersion !== "latest"
// "oh-my-opencode@3.5.2" → isPinned = true (same result for installer and user)

Additionally, the toast message "Restart to apply" is misleading — restarting does nothing because the config file was never modified.

Error Logs

No errors in logs — the auto-updater silently skips the update and only shows a toast.

Additional Context

Timeline of related issues:

Issue	Date	Effect
#402	Jan 2	Requested auto-update → implemented (overwrites all versions)
#1745	Feb 11	Reported overwrite bug → fixed by skipping isPinned=true
This issue	Feb 17	Side effect: installer-pinned users also skipped → no auto-update for anyone

Evidence from source code:

• tui-installer.ts / cli-installer.ts: addPluginToOpenCodeConfig(version) always writes exact version
• plugin-entry.ts: isPinned = pinnedVersion !== "latest" — no way to distinguish installer vs user
• background-update-check.ts: if (pluginInfo.isPinned) { return } — skips update entirely

Possible solutions:

1. Installer writes "oh-my-opencode" (unpinned) instead of "oh-my-opencode@X.Y.Z"
2. Installer writes "oh-my-opencode@latest" — already treated as unpinned by isPinned logic
3. Add metadata (e.g., "installer_managed": true in oh-my-opencode.json) to distinguish intent
