audit: #328 cycle close — manifests record raw on every route, walkforward intake refuses wrapped

Architect drift review (cycle a3785a6..b3b7115) found the cycle's raw
switch incomplete on two high items; both fixed forward here rather
than minuted as residue, since #319 builds on this namespace:

- The real/campaign executor still minted WRAPPED manifest.params and
  manifest.defaults (AC2 overclaim in the feat commit body). The mint
  seams now reshape to raw on every route (member.rs raw_bound_defaults,
  runner.rs manifest_space mirror of the family.rs pattern); the fix
  surfaced a latent regression in persist_campaign_traces, which keyed
  point_from_params by exact wrapped name and is now translation-aware
  (same recipe as reproduce_family_in). Old on-disk families stay
  replayable (C29; reproduce reads both shapes).
- The walkforward --axis intake silently accepted wrapped names — the
  silent alias fork 2 rejected. It now runs the same
  refuse_wrapped_synthetic_axes preflight as the plain synthetic sweep
  (new e2e: aura_walkforward_synthetic_blueprint_refuses_a_wrapped_form
  _axis_name); family builders translate raw names onto wrapped
  SweepBinder slots on all three entry points. C24's "retired from the
  surface" claim is thereby made true instead of softened.
- Low items: stale graph_construct docstring updated; new
  graph_params_and_sweep_list_axes_are_line_identical pins the two
  discovery surfaces against format drift.
- Bench infra: aura-bench's campaign_sweep surface seeded wrapped axis
  literals and was correctly refused by the new intake — seeds converted
  to raw; full bench rerun: all 5 surfaces fingerprint OK, deltas within
  load noise (report-only, no baseline update needed).

Library-unit tests calling family builders directly keep wrapped input
(valid: translation is idempotent on exact wrapped names; intake-level
refusal is the user contract). Suite + clippy verified green post-fix.
