feat: add CLI subcommands for recovery agent management

[agentotto]

Summary

Adds a walletkit recovery-agent subcommand group to the CLI with three actions for managing recovery agent updates:

• recovery-agent initiate <new_recovery_agent> — initiates a time-locked recovery agent update (14-day cooldown). Takes the checksummed hex address of the new recovery agent.
• recovery-agent execute — executes a pending recovery agent update after the cooldown has elapsed (permissionless).
• recovery-agent cancel — cancels a pending recovery agent update before the cooldown expires.

Each command delegates to the corresponding Authenticator method added in #320 and prints the returned gateway request ID. Supports --json output.

Changes

• walletkit-cli/src/commands/recovery_agent.rs — new module with RecoveryAgentCommand enum and run dispatcher.
• walletkit-cli/src/commands/mod.rs — registers the RecoveryAgent variant in Command and wires up dispatch.

Usage

# Initiate a recovery agent update
walletkit recovery-agent initiate 0xNewRecoveryAgentAddress

# Execute after cooldown
walletkit recovery-agent execute

# Cancel before cooldown expires
walletkit recovery-agent cancel

# JSON output
walletkit --json recovery-agent initiate 0xNewRecoveryAgentAddress

---

Note

Medium Risk
Adds new CLI flows that trigger recovery-agent update operations via Authenticator; mistakes in argument validation or the exposed command name could lead to user confusion or unintended update requests.

Overview
Adds a new recovery-agent-update command group to walletkit for managing recovery agent updates, wiring it into top-level command dispatch.

Implements initiate, execute, and cancel subcommands that call the corresponding Authenticator methods and print the resulting request_id in either human-readable form or the existing --json envelope.

/otto resolve CI issues

[agentotto]

Fixed CI in commit 1c042e7. Two issues were found and resolved:

1. cargo fmt failures — formatting was off in both mod.rs and recovery_agent.rs (multi-line blocks that rustfmt wanted collapsed).

2. Clippy enum_variant_names — all three variants of RecoveryAgentCommand shared the Update postfix, which clippy rejects under -D clippy::all. Renamed:

   • InitiateUpdate → Initiate
   • ExecuteUpdate → Execute
   • CancelUpdate → Cancel

This also aligns the actual CLI subcommand names with what the PR description advertised (recovery-agent initiate, recovery-agent execute, recovery-agent cancel). All checks passed locally (fmt, all three clippy configurations, and cargo test -p walletkit-cli).

/otto in that case let's rename it the recovery-agent commadn to recovery-agent-update
