chore: release v2.4.3

Ships the Steward capability-extraction fix (a905363), which has been on
main since earlier today while production continued to route on prose:
the running v2.4.2 still matches capability domains as substrings across
the Steward's whole response, so "description" selects housekeeper and
"acknowledge" selects librarian and biographer.

Patch rather than minor: no new capability, and the JSON on the wire is
unchanged. What changes is which agents get invoked, and only in the
cases that were already wrong.

Also carries the routing benchmark, its fixtures, the shared GPU
residency guard and the findings document, none of which are
user-visible.
