fix(aura-cli, ledger): review fixes — override stamps the base hash (#343 revised), prose corrections

Harvest sweep, whole-diff review fix block.

The review refuted the #343 ratification's factual premise: the
campaign leg does NOT mint a reopened member's hash — runner.rs passes
the stored strategy_id as topo even for reopened members (reference
semantics). Decision revised on the issue (fix, not ratify): exec's
override run now stamps the LOADED base document's content id
(computed before reopen_all; RED-first — the inverted pin failed on
the old reopened-hash behaviour), keeping topology_hash
store-resolvable and identical in meaning across both legs; the
variation lives in manifest.params. C24/C12/C18 rewritten to the
corrected reading.

Also per review: C24's retired build-free-introspection sentence
updated (old wording archived in the history sidecar, #339 item 4);
C14's partition key precisely scoped to the routing seam, naming the
legs' differing content-validation exits honestly; measure.rs's false
unreachability comment corrected; --taps added to the guide's
introspect cheat-sheet and pinned on the content-id path; the
zero-trade-cell note routed through the diag macro; doc-comment,
issue-ref, and gate-name corrections; the Fixed-regime NaN branch
pinned.

replay; build-free introspection paths pass `&|_| None`. The echo
replay; the CLI's introspection paths resolve `use` refs through the store
exactly like `graph build` does (`parse_and_resolve_ops`, the shared first
phase both callers run — #339 item 4 harvest retired the earlier build-free
`&|_| None` resolver on the introspection side). The engine's closure
contract above is unchanged: only the CLI-side caller supplied for
introspection now always threads a real store-backed resolver. The echo
(`aura: note: use "<instance>": <label-or-prefix> -> <full id>`) is the existing
`aura: note:` benign-diagnostic marker (C14) — a new instance of the existing
class, not a new one, so the exit-code/marker taxonomy is unchanged.
