Completes FLUID-WP-0004. The Revision and Intent APIs (Blueprint 44.1
and 44.5) are served by fluid-control, which is deliberately off the
request path and must never be reachable by interface consumers: it is
the mechanism that evolves the interface in response to their behaviour.
Intent amendment is a proposal, never an edit. Rewriting a recorded
version returns 409, because changing what a version says would change
what already-published revisions were governed by.
A rejected candidate comes back as 422 with its full stage report rather
than as a server fault. Rejection is a normal outcome (invariant 14) and
the reasons are the evidence a later hypothesis needs.
Also closes a real hole this workplan opened: `fluid revision publish`
previously wrote straight into the evidence store, which was a way
around the deterministic policy gate for anyone with shell access. It
now runs the same pipeline the control plane does and requires a signing
key.

Completes FLUID-WP-0003. The evidence store is append-only at the
database, not by convention in Go: a trigger blocks UPDATE and DELETE on
fluid_events in both SQLite and Postgres, so the guarantee binds a psql
session and the CLI equally, not just callers who go through the Go API.
Records are derived summary state and may be superseded; the event log
stays the authority.
The intent store makes a recorded version immutable and content
addressed, since reassigning what governed a revision after the fact
would break the one audit question Blueprint 27 exists to answer. The
unfilled InterfaceEvolutionIntent template is rejected rather than
defaulted, because a template still listing every FLUID-N mode has not
been completed and defaulting it would pick a permissive authority by
accident.
The CLI reads the evidence store directly rather than through the
control-plane API, so an operator can reconstruct history when the
control plane is down.
