fix: --no-color CLI flag not consulted by TUI wizard

[MacAttak]

Problem

isColorDisabled() only checks NO_COLOR and CI environment variables and is evaluated once at BuildRootCommand() time. The --no-color persistent flag registered in root.go is never consulted, so passing --no-color on the CLI has no effect on the wizard's accessible mode.

Context

Raised in PR #14 review (comment). Deferred because the fix requires changing Wizard.Run to accept the accessible setting lazily (or accept a func), which widens scope.

Suggested fix

Check --no-color inside runInit after Cobra has parsed flags, and pass it to the wizard:

// In runInit, after parsing flags:
noColor, _ := cmd.Flags().GetBool("no-color")
wizResult, err := cfg.Wizard.Run(cmd.Context(), isColorDisabled() || noColor)

This requires updating the initWizard interface and Wizard.Run signature.
