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.
