fix(cli): route cdk destroy through toolkit-lib

[mrgrain]

Routes cdk destroy through the toolkit-lib destroy action, the same way cdk list was rerouted, and removes the legacy CdkToolkit.destroy implementation.

User-facing output and behavior are unchanged. The CLI keeps the destroy output identical with CliIoHost listeners:

• suppresses the toolkit-lib synthesis/destroy lifecycle lines the CLI never showed (it keeps emitting its own synth lines)
• keeps the success line at info (toolkit-lib emits it as result)
• --force auto-confirms the deletion prompt without showing it
• a declined confirmation still exits non-zero with a soft "Deletion cancelled"

toolkit-lib behavior is unchanged: its destroy action still logs the declined confirmation and returns, and the CLI turns that into the non-zero exit (by throwing from the E7010 listener). The action label is preserved so a destroy triggered by a deploy still says "deployed", via a private _destroyWithAction.

The destroy IO-snapshot tests assert the recorded user-facing stream is unchanged.

Technical details

• IO-snapshot recorder now omits listener-suppressed (dropped) messages by default, and requestResponse marks a suppressed prompt as dropped, so snapshots contain exactly what the user sees.
