Description

Description
When importing a local .bpf profile file on iOS by tapping it and selecting the sing-box app to open it, the app does not import the profile. Instead it shows a Taildrop / Tailscale-related prompt and the profile import does not happen.

My configuration does not use a Tailscale endpoint at all, so this appears to be the app's file-open handler incorrectly routing the incoming file to the new Taildrop feature (added in 1.14.0) instead of the profile import flow.

This may be related to #3750, which reports a similar regression on Android (tapping a .bpf file no longer auto-imports it), though the symptom there is a silent no-op rather than a Taildrop prompt.

Expected behavior
Tapping a .bpf file and opening it with sing-box should import it as a profile, as in previous versions.

Actual behavior
The app shows a Taildrop-related prompt and does not import the profile.

Configuration
No Tailscale endpoint is configured.

Additional context
Screen recording attached showing the behavior.

Reproduction

Reproduction

1. Export or receive a .bpf profile file on iPhone (e.g. via AirDrop, Files, or email attachment).
2. Tap the file in Files/Mail/wherever it was received.
3. Choose "sing-box" from the Open With / share sheet.
4. Observe: a Taildrop/Tailscale-related screen appears instead of the profile import screen.

Reproduce the issue on the iOS graphical client by opening a local .bpf file and selecting sing-box. Trace the iOS file-open handler added around the 1.14.0 Taildrop feature and its routing to profile import; done means the file opens the profile import flow without a Tailscale endpoint.
