darmanandClaude Opus 5 c18413d16d hermes: write the webhook routes as config, and add a PR-review route
`hermes webhook subscribe` has no --toolsets flag, so a webhook run got
Hermes's constrained default (web_search, web_extract, vision_analyze,
clarify) -- no shell, no file access, which meant neither prompt could
actually be carried out: luna was woken, read the comment, and had no way
to act on it. Upstream's documented answer is to add the `toolsets` key to
webhook_subscriptions.json by hand, and a hand edit does not survive this
unit's re-provision. So the whole route definition moves here and the CLI
is not used at all.

The file is written host-side with jq. hermesHome is the bind-mount source
for /opt/data, so the container sees the same inode and hot-reloads it on
the next delivery -- no podman exec, no readiness loop, and no quoting
chain between nix and the prompt text. The merge is per-route: routes this
unit does not name survive, created_at is carried over, and every other
key is replaced outright so a hand-added `deliver_only` or `filters`
cannot linger.

The secret now comes from the sops file directly instead of being read
back out of the container's environment, which drops podman-hermes-agent
from restartUnits (the ordering constraint it existed for is gone) and
takes GITEA_HERMES_WEBHOOK_SECRET out of an env var luna can read.

The new gitea-pr-reviews route covers reviews with a body and
changes-requested. Those are not IssueCommentPayloads: gitea sends a
PullRequestPayload with action "reviewed" and a `review` object of exactly
{type, content} -- no review id, no line comments. So the prompt fetches
them with `tea pulls review-comments` and acts only on ones whose
`resolver` is empty, resolving each as it goes; with no stable id in the
payload, resolved state is the only workable duplicate-delivery guard.
An empty review body is deliberately NOT a drop, unlike in the comment
filter: a review whose substance is entirely in line comments has none.

Approvals are left unsubscribed -- an approval is darman signing off, not
asking for work.
