Problem

Nightly CI fails across all six profiles during PDP upload with HTTP 500: no hash space range owns this hash. Curio discovers long-term storage when initializing its hashspace, but devnet registered storage only after starting the daemon.

Changes

• Initialize fast/long-term storage metadata and register container-visible paths before launching Curio.
• Preserve existing storage IDs, policies, and pieces.
• Replace post-start attachment and fixed startup sleep with RPC readiness. No restart required.
• Document the startup ordering and add storage-preservation regression coverage.

Verification

• cargo check --locked passed.
• cargo test --locked commands::start::curio::storage::tests::repeated_setup_preserves_existing_storage -- --exact passed.
• Throwaway offline smoke check confirmed generated registration and long-term storage eligibility for hashspace discovery.
• Did not run foc-devnet locally; CI provides end-to-end verification.

🟡 Changes recommended

The readiness command can abort setup during normal cold starts, and overwriting storage registrations can make previously attached storage inaccessible after restart.

What changed in this PR

Moves Curio storage initialization ahead of daemon startup so PDP hashspace discovery can include long-term storage on the first launch.

Changes:

• Creates storage metadata and registers container-visible paths before starting Curio, preserving existing metadata.
• Replaces post-start storage attachment and the fixed startup delay with an RPC readiness command.
• Documents the startup order and adds regression coverage for preserving storage identities, policies, and pieces.

Initial CI run: lint and cargo tests passed; integration failed immediately after Curio launch because wait-api returned connection refused before the RPC listener started. Upstream wait-api can return immediately on RPC/version errors. Added the existing bounded fixed-delay retry helper around this read-only readiness probe. Offline smoke verification covers initial refusal followed by success and persistent refusal exhausting the retry limit. No local foc-devnet run.

Latest CI is green on 4b95135: lint, cargo tests, and the full devnet startup/scenario integration job all passed. Both review comments are addressed and resolved.
