feat(pm-agent): an in-cluster AI Program Manager that turns Gitea issues into pull requests
A service that reads this repository's Gitea issues, decides what to do about each
thread as the Program Manager persona, and runs one worker agent per assignment that
authors a change, runs the merge gate and opens a pull request. It reacts to issue
creation and to comments; the assignment and all correspondence travel through the
issue thread and the PR. It authenticates with an Anthropic subscription token. It
never pushes to main and never merges.

Three choices carry the design, with alternatives recorded in docs/plans/:
 - it POLLS rather than receiving webhooks (Gitea's webhook SSRF guard, lost
   deliveries, and no inbound reach needed at all);
 - it keeps NO state: the trigger is "the newest thing in this thread was not
   written by me", so the issue thread is the state — no PVC, no backup obligation;
 - the model holds NO tools: its reply is one JSON object this code validates, so
   nothing in the path executes text.

The boundary is platform/kyverno/admission/pm-agent-job-shape.yaml (Enforce,
failurePolicy: Fail), not the RBAC: Kubernetes places no `use` check on
serviceAccountName, so "may create Jobs" is "may run arbitrary code as the
namespace's most privileged identity". Six rules admit only the committed shape, and
the worker identity is bound to nothing with no token mounted, so there is nothing to
escalate to. 28/28 offline Kyverno assertions.

Nothing has run: the image has never been built or pushed, and both the image digest
and the two credentials are deliberate placeholders. See the handoff entry's
"What I did NOT verify".

# Flux Kustomization: the PM agent service — reconciles ./platform/pm-agent.
#
# POST-APP TIER (dependsOn apps-wave-0). What this service actually depends on is GITEA: the
# dispatcher authenticates to it at startup, reads issue threads from it, and every worker
# clones and pushes to it. Gitea is in apps-wave-0, so that is the dependency — not
# platform-config, which brings up the Keycloak realm, the wildcard certificate, the Gateway
# and the L2 pool. This service has no UI, serves no traffic, takes no ingress and holds no
# certificate, so none of those are prerequisites and claiming them would be a lie that
# delays its reconcile behind four things it does not use.
#
# NON-GATING (wait:false), and here that is not merely prudent — the pod is EXPECTED to be
# unhealthy for a while:
# * the committed credentials are PLACEHOLDERS, so until the operator replaces them the
# dispatcher fails its Gitea authentication at startup and CrashLoops, by design
# (platform/pm-agent/pm-agent-credentials.sops.yaml.example);
# * the image digest is likewise a placeholder until the operator pushes the image, so
# before that the pod cannot even pull.
# Either of those inside a wait:true tier would stall everything downstream of it. wait:false
# guarantees this service's health can NEVER gate anything, even if some future resource is
# mistakenly pointed dependsOn it. Same non-gating leaf rationale as
# headlamp/homepage/crafty/backup — with a stronger reason than any of them.
#
# PRUNE: true. The whole namespace is disposable — the dispatcher keeps no durable state (the
# Gitea issue thread is its state) and worker Jobs are ephemeral by construction. So removing
# this service from git really should remove it from the cluster, with nothing to orphan.

# token today, and the two scripts that DO contain shell live in the image, not in a
