fix(prism): queue submits when lium b200s sell out

[echobt]

Summary

• Lium no_capacity / sold-out / no matching 1× B200 offer requeues the submission (no retry_count burn, not Score(0)) instead of failing closed.
• Miner-facing note: B200s are currently out of capacity on Lium; this job is queued until an offer appears. (events + error_detail; intake + GET /v1/status carry the queue policy).
• Template-permission / auth / bad ZIP still fail (Lium already retries a rentable template once). BYOK unchanged. Next claim_next tick retries rent; failed sold-out rows are recovered by the existing 429 recovery loop.

Test plan

• no_capacity → stays queued + B200 note; second tick still queued
• 400 template permission → failed (auto_retry_max: 0)
• Happy-path sim orchestrator still terminates
• Intake 202 includes capacity policy note; /v1/status has lium_capacity_note

Summary by CodeRabbit

• New Features

  • Submissions encountering temporary capacity shortages or sold-out B200 hardware are now re-queued automatically.
  • Capacity retries do not consume retry attempts and include a capacity-specific status note.
  • Status responses now expose capacity guidance through lium_capacity_note.

• Bug Fixes

  • Authentication, permission, invalid ZIP, and other terminal failures remain correctly excluded from capacity retry handling.

• Documentation

  • Updated orchestration and API documentation to describe capacity-based retries and status reporting.

📝 Walkthrough

Walkthrough

Lium capacity failures now use dedicated classification and recovery behavior. Affected submissions remain queued, do not consume retry attempts, record capacity details, and expose the policy through API responses and documentation. Authentication, permission, ZIP, and other non-capacity failures remain terminal.

Changes

Lium capacity recovery

Layer / File(s)	Summary
Capacity classification and recovery policy crates/lium-rent-pool/src/lib.rs	Adds capacity-policy constants and classifiers for capacity versus authentication or permission failures. No-capacity failures recover immediately.
Queued retry orchestration and validation crates/prism-challenge/src/orchestrator.rs, crates/prism-challenge/tests/e2e_orchestrate_sim.rs, bins/prism-challenge/src/main.rs, crates/prism-store/src/store.rs	Capacity retries preserve retry counts, record capacity metadata, and keep submissions queued. Tests cover capacity requeues and terminal template-permission failures.
Capacity status and external behavior crates/prism-challenge/src/api.rs, docs/PRISM.md, docs/external-miner/prism.md	Accepted responses and /v1/status expose the capacity policy. Documentation describes queued B200 capacity handling and terminal non-capacity failures.
