Exit UX Improvements

Peterrequested to merge
bugfix/no-auto-exit into master
  • check or remove this line after you've added a CHANGELOG entry or if your PR doesn't need one (they should go into CHANGELOG/unreleased/)

Some assorted improvements for the exit system:

  • Add a new VtxoState to explicitly call out when a VTXO has been exited
  • No longer lock or mark a VTXO as spent when starting an exit
  • The exit movement status remains in pending unless its claimed or the VTXO has been spent offchain
  • Automatically mark a VTXO as exited when the exit has been fully broadcast so the user can't try spending it unsuccessfully

Summary by CodeRabbit

  • New Features

    • Introduced an explicit Exited VTXO state and a terminal "VTXO already spent" exit state; exits are now created pending and finalized later. Added movement tracking and a wallet API to mark VTXOs as Exited.

  • Bug Fixes

    • VTXOs remain spendable while exit transactions broadcast; exits detect already-consumed VTXOs and cancel without blocking funds.

  • Documentation

    • Clarified pending-exit balance and API docs to reflect new exit/VTXO lifecycle.

  • Chores

    • Database migrations and tests to backfill and migrate exit/movement data.
