Per-tab folder destination and HTMX FuckingFast resolve

[MehdiMamas]

Summary

• Resolve FuckingFast landing pages via HTMX hx-post=/f/{id}/go (plus legacy /dl/), with https-only fetches and spacing to avoid Cloudflare 429s
• Per FitGirl-tab destination via native showDirectoryPicker, stored as a DirectoryHandle (cleared when the tab closes)
• Download through an offscreen worker with File System Access writes (absolute folders), plus pause/cancel/retry and full file-list restore after a finished batch

Test plan

• Load unpacked extension on a FitGirl page with fuckingfast.co parts
• Choose a Windows folder, select parts, start downloads into that folder
• Pause / resume / cancel mid-batch; retry failed items
• Confirm UI returns to the full file list after the batch finishes (not stuck on last-run subset)
• Open a second FitGirl tab, pick a different folder, run both batches concurrently
• Close a tab and confirm its destination handle is forgotten
