feat(compound-engineering): CE flow renderer, stage launcher, audit (U6)

Extend the stage registry with presentation metadata (icon/label/glob) so adding
a stage stays data-only. Add CeFlow renderer for text/single_select/multi_select/
confirm questions over the U5 polling session routes, with a visibly-marked chat
fallback (AE1) that still completes the stage. Wire the artifact-hub launcher to
list and start registered stages. Add the skill-interaction audit test producing
a measured rich-vs-chat coverage ratio (declared classification: 8/8=100% across
brainstorm/ideate/plan), failing on unclassified interactions.

*
* CLASSIFICATION PROVENANCE — be honest. This audit is a DECLARED /
* EXPECTED classification, NOT a measurement taken from driving live `ce-*`

* each stage performs are read from each stage's protocol — the SKILL.md
* "Interaction Rules / Interaction Method" sections that govern how the skill
* asks questions (e.g. ce-brainstorm: "Ask one question at a time", "Prefer
* single-select", "Use multi-select rarely", open-ended free-text questions;
* ce-ideate / ce-plan: single-select-preferred + free-text). Each declared
* interaction is then classified against CeFlow's renderable set
* (`RICH_INTERACTION_TYPES`) to compute a rich-vs-chat coverage ratio.
*
* The test FAILS if any sampled interaction is unclassified (a type CeFlow's
* support module doesn't recognize at all), which is the guard that keeps the
* audit honest as the skills' protocols evolve. When a stage declares a
* confirm/text/single/multi interaction, that is rich-renderable; an
* "unknown_type" declaration would be unclassified and fail.
