* feat: content tab improvements — upload UX, installation settings, and client-only indicators

   Upload cancellation and navigation guard:
   - Add ConfirmLeaveModal that prompts when navigating away during upload
   - Cancel in-flight XHR uploads when user confirms leaving the page
   - Add beforeunload handler to warn on browser/tab close during upload
   - Track uploadedBytes/totalBytes in UploadState for progress display
   - Replace Collapsible with Transition for upload progress admonition
   - Show byte progress and percentage in upload banner
   - Clamp upload progress to prevent exceeding 100%

   Installation settings (server.properties):
   - Add KnownPropertiesFields and PropertiesFields types to Archon types
   - Add buildProperties() to creation flow context to collect gamemode,
     difficulty, seed, world type, structures, and generator settings
   - Pass properties through installContent on onboarding, discovery, and
     ServerSetupModal flows

   Server setup and discovery flow improvements:
   - Migrate ServerSetupModal from servers_v0.reinstall to content_v1.installContent
   - Replace loaderApiNames lookup with toApiLoader() helper
   - Remove eraseDataOnInstall toggle — always use soft_override: false
   - Simplify modpack install on discovery page to use first available version
     and route through creation flow modal for both onboarding and non-onboarding
   - Differentiate post-install navigation: content page for onboarding,
     loader options for existing servers

   Modpack update flow:
   - Replace updateModpack() call with installContent() using soft_override: true
     to support version selection in the content updater modal

   Client-only mod indicators:
   - Add environment field to AddonVersion (reuses Labrinth.Projects.v3.Environment)
   - Add environment to ContentItem and isClientOnly to ContentCardTableItem
   - Show orange TriangleAlertIcon with tooltip on client-only mods in content table
   - Add "Client-only" filter pill to content filtering (controlled via
     showClientOnlyFilter on ContentManagerContext)
   - Apply client-only indicators in both ContentPageLayout and ModpackContentModal

   Misc:
   - Add CLAUDE.md note about using prepr commands for lint checks
   - Export ConfirmLeaveModal from instances barrel

+## Edit Tool - Whitespace Handling (CLAUDE ONLY)
+
+The Read tool uses `→` to mark where line numbers end and file content begins.
+
+**Rule:** Copy the EXACT whitespace that appears after the `→` marker.
+- Whatever appears between `→` and the code text is what's actually in the file
+- That whitespace must be used EXACTLY in Edit tool's old_string
+- Don't count arrows, don't interpret - just copy what's after the `→`
+
+**Example:**
+14→		private byte tag;
+For Edit, use: `		private byte tag;` (copy everything after →, including the two tabs)
+
+**If Edit fails:** Stop and explain the problem. Do not attempt sed/awk/bash workarounds.
+
+**IMPORTANT**: Trust the Read tool output. Copy what's after `→` into Edit immediately. DO NOT verify with sed/od/grep first - that's wasting time and the instructions already tell you to stop if Edit fails, not to pre-verify.
