Implement the response submit placeholder

Labels: cli, feature, priority/high
Difficulty: High · Effort: L
Backlog slot: 50

Problem Statement

response submit <file> prints "💡 Full submission implementation coming soon".

Why it Matters

• Without submit, the entire wallet-signing flow is dead-ended.

Expected Outcome

1. Parse signed tx JSON.
2. Connect to configured RPC.
3. Submit + wait for confirmation.
4. Surface tx hash + status in human form.

Acceptance Criteria

• End-to-end test on testnet confirmed tx hash returned.

Files Likely Affected

• crates/tools/src/response.rs (or new module)

Dependencies

Issue #48.
