feat(runner, cli, research): metric/tap schema carriers + the C29 coverage walk

C29 compile/unit seam, tasks 6-10 -- iteration 1 of the self-description
plan complete: every engine-shipped vocabulary entry now carries a
gate-clean one-line meaning.

- aura-runner: the internal tap recording sink threads its doc (the
  last unthreaded NodeSchema site) -- first full workspace build since
  the field became required.
- aura-cli scaffold: the sample node's template carries a doc line plus
  a maintenance comment, so every scaffolded extension crate starts
  gate-clean; both extension-vocabulary fixture exemplars thread real
  meaning lines (the load seam walks these in iteration 2). New E2E:
  the scaffold's own doc must pass its own gate -- an alibi doc in the
  template would teach the wrong pattern to every new project, and the
  compiler checks only the field's presence, never its shape.
- aura-research: metric_vocabulary()/tap_vocabulary() promote from bare
  name arrays to MetricSchema/TapSchema carriers (id + doc, 17 + 4
  authored lines); callers adapt to .id with byte-identical output
  (introspection goldens unchanged). The #190 guard keeps its triple --
  the doc column adds no fourth roster site.
- Coverage: tests/self_description.rs walks all five vocabularies
  (blocks, metrics, taps, folds, std nodes) through doc_gate -- the
  guard that keeps any future edit from blanking a doc.

Adjudicated review residue: the 17 metric doc strings are surfaced by
no CLI path yet -- deliberate; task 8 pins callers byte-identical, the
surfacing belongs to the CLI self-description work (#315). Plan-cited
coordinates lib.rs:1003/:1283 resolved to the real caller sites
(:1019/:1299); the plan's literal test code was reconciled to the real
accessors (FoldRegistry::core().roster(), Env::std()).

Gates: cargo test --workspace green (0 failed, incl. the new coverage
walk + scaffold E2E); cargo clippy --workspace --all-targets --
-D warnings clean.
