Add interactive preset picker

[mintyPT]

Problem

The CLI has many useful built-in presets, but users need to know which preset and flags they want before they can make progress. clickclick preset list is descriptive but not an authoring workflow.

Proposal

Add an interactive preset picker, for example:

clickclick preset browse
clickclick init image

The flow should let users choose a preset, enter required fields, optionally provide common media/color options, preview the result, and emit either the final CLI command or a config recipe.

Acceptance criteria

• Users can browse built-in presets from the CLI.
• Required preset options are prompted for.
• The generated render can be written to an output path.
• The flow can print the equivalent non-interactive command.
• The implementation reuses existing preset metadata/schema where practical.
