Description

This PR is dependent on #38, we need it merge it first

Integration testsI: 222 tests across 8 suites that spawn the real bin/wdk.mjs against a throwaway config directory.

suite	commands	also covers
wallet	create, import, unlock (+ session ttl), lock, export, list, default, rename, delete, change-passphrase	a session when a module is disabled; the passphrase gate itself
network	list, create, info, enable, disable, delete	networks hidden by a disabled module; passphrase gate
token	list, info, add, delete, enable, disable	a hand-edited registry; a token a command has to resolve; a disabled token through network and module cycles; passphrase gate
module	list, add, remove, enable, disable, methods	passphrase gate
provider	list, info, add, enable, disable, delete	single-instance kinds; a provider hidden by a disabled module; provider config through a module cycle; a user-added provider in use; passphrase gate
config	path, get, set, reset	file permissions; passphrase gate; the wallet lock a config change forces
read-operations	get address, message verify	deriving on a network whose module is disabled
write-operations	message sign, send, swap, bridge, buy, sell	no provider for the kind; choosing the provider with --provider

Fixes

• Deleting a provider left its config behind. Because you can reuse the name, the next provider added under it picked up the old settings
• Split WalletDaemon.shutdown() into close() + exit, so a caller that owns the process can release resources without terminating.
• config.json is now written 0600 and its directory 0700 since It holds provider API keys;
