/**
 * outdated-cost-hooks migration: re-install cost hooks whose command text is not
 * what this version writes.
 *
 * `legacy-cost-hooks` answers one historical question — does this hook predate the
 * shim? — and had to be written when that change shipped. This one answers the
 * question that recurs: is the installed command current? Every future
 * command-shape change is then repaired by machinery that already exists, instead
 * of by another bespoke detector nobody remembers to add.
 *
 * The change that prompted it: the claude-code SessionEnd hook now passes
 * `--session-end`, so the recorder drops the ending session's active-session stash
 * entry. An install without the flag is not broken — `cost record` also accepts the
 * `hook_event_name: "SessionEnd"` signal in the payload, which is deliberately what
 * makes the fix land without a re-install — but it should not stay behind.
 *
 * Same narrow warrant as `legacy-cost-hooks`: it only ever replaces hook entries
 * carrying our own `#aidlc-cost-hook` marker, through the merge-not-clobber
 * installer, so nothing the user wrote is touched. Self-clearing — after the
 * re-install the status reads current.
 *
 * Ordered after `legacy-cost-hooks`, which re-installs and therefore leaves those
 * platforms current: each migration then reports only its own condition.

 * Only installed hooks count: an absent hook was never armed, which is a different
 * condition that `aidlc cost hooks status` already reports.
