fix: suppress hook warning during rtk init and verify

[JackDanger]

Problem

Running rtk init -g printed a spurious warning:

[rtk] /!\ No hook installed — run `rtk init -g` for automatic token savings

This happened because maybe_warn() fired before the init completed.

Fix

Skip maybe_warn() for Init and Verify commands — they manage the hook themselves and don't need the reminder.

if !matches!(
    cli.command,
    Commands::Gain { .. } | Commands::Init { .. } | Commands::Verify { .. }
) {
    hooks::hook_check::maybe_warn();
}

Test plan

• rtk init -g no longer shows the hook warning
• rtk verify no longer shows the hook warning
• Other commands (e.g. rtk git status) still show the warning when hook is missing
• cargo test --all passes (1606 tests)
