Add TARDIS homeward protocols

[Peter1169]

About the PR

This adds automatic homeward and recovery protocols for unattended or inaccessible TARDISes. It is separated from #2166, which now only handles configuring and manually targeting a TARDIS home.

Automatic journeys only begin while the handbrake is disengaged and the TARDIS is outside its configured home area, unless the recovery exists specifically to restore an inaccessible exterior.

• A TARDIS which runs out of fuel can use Emergency Power or wait while refuelling until it can return home.
• Breaking into an unpowered TARDIS with an axe below PILOT loyalty can trigger an automatic Artron Dump and crash landing at home after the intruder enters.
• Hail Mary now completes a full rescue flight, closes its doors before departure and can return home after the rescued player enters.
  • Optional fall and void rescue materializes at the player's position, enables antigravity and pulls them towards the exterior.
  • The original animations, alarm persistence and autopilot state are restored after the rescue.
• An empty TARDIS abandoned in the Nether by a passenger below PILOT loyalty can return home after a short randomized delay.
• An empty TARDIS can flee tagged bosses, refuel at home and return after the original location has remained safe for 60 seconds.
• A Ghost Monument TARDIS left unattended outside its home area returns to its exact home without consuming fuel.
• A TARDIS left in siege mode for 33 ingame hours can relocate its siege representation home while remaining in siege mode.
  • This supports placed siege blocks, item entities, player and block inventories, inventory-owning entities and nested container NBT.
• A landed TARDIS whose interior still exists but whose exterior cannot be found restores the exterior at home.
• Automatic landings use bounded safe-position searches with an exact-home fallback when no valid nearby position exists.

Why / Balance

These protocols prevent unusual states from making a TARDIS permanently inaccessible while preserving player control and normal travel costs.

The handbrake acts as the direct opt-out for applicable automatic movement. Entering a TARDIS cancels pending unattended recovery where player control should take priority. Accelerated journeys calculate their real cost before reducing flight time and still pay that cost on arrival; insufficient fuel leaves the TARDIS empty and powered down.

Nether returns, boss journeys and post-Hail-Mary returns use normal flight speed. Artron Dumps retain their own damage and crash consequences. Only Ghost Monument and missing-exterior recovery are fuel-free because they restore states which could otherwise strand the TARDIS.

Technical details

• Added a persistent ReturnHomeHandler for recovery state, automatic travel, fuel recovery, Hail Mary state, threat tracking, siege relocation and missing-exterior restoration.
• Added instant, normal, free, deferred-cost and Artron Dump travel modes.
• Automatic travel forces autopilot and suppresses random gameplay flight sequences while preserving lifecycle events used by existing integrations.
• State is serialized and safely resumed or cancelled after reload.
• Landing searches are bounded and use request identities so stale asynchronous callbacks cannot materialize a TARDIS twice.
• Dormant TARDIS audits are staggered and release cold-loaded instances after their recovery state has been checked and persisted.
• Boss checks temporarily ticket only the required chunks and release those tickets after completion or cancellation.
• Siege inventory traversal has explicit recursion and node limits, validates locator hints before mutation and uses rollback to prevent item loss or duplication.
• Added generated English and Spanish text for every new status, configuration option and Handles response.

🆑

• feat: Unattended TARDISes can now use configurable homeward protocols when they run out of fuel, are abandoned in the Nether, encounter a boss or remain in Ghost Monument or siege mode for too long.
• feat: Hail Mary now performs a complete rescue flight and can return the rescued player to the TARDIS home, with an optional fall and void rescue.
• fix: Missing TARDIS exteriors can now be restored at their configured home instead of leaving the TARDIS inaccessible.
• tweak: Automatic journeys retain their calculated AU cost when accelerated and use bounded landing searches with a safe exact-home fallback.
