T8764: add per-repo CodeRabbit config — Jira VD project scope

Add `.coderabbit.yaml` at repo root with the minimum override needed
to (a) opt the VyOS-Networks mirror into the central Jira integration
and (b) scope it to the VD (VyOS Dev) project.

Cross-org behavior using `usage: auto`:

* On `vyos/vyos-1x` (this repo, public): `auto` self-disables on
  public repos, so no Jira context is fetched. The vyos-org
  CodeRabbit install has no Atlassian OAuth grant anyway — CodeRabbit
  allows one GitHub-org → Jira-tenant link per install, and that link
  is attached to the `VyOS-Networks` org.
* On `VyOS-Networks/vyos-1x` (gen-1 mirror, private/internal): `auto`
  activates the integration and `project_keys: [VD]` restricts the
  context to VD tickets only — matching the project keys used in
  release-train work tracked there.

Everything else (review profile, tools, chat ACL, path filters,
finishing-touches behavior, etc.) continues to inherit from the
respective central baseline:
  - https://github.com/vyos/coderabbit/blob/production/.coderabbit.yaml
  - https://github.com/VyOS-Networks/coderabbit/blob/production/.coderabbit.yaml

Pattern note: this is the canary for the source-of-truth-on-vyos
approach. Once it lands clean, the same file (with the same or
slightly different `project_keys`) should be mirrored to the other
vyos-org source repos that have VyOS-Networks mirrors.

+# Per-repo CodeRabbit override for vyos/vyos-1x.
+#
+# Most behavior is inherited from the org-level central baseline at
+# https://github.com/vyos/coderabbit/blob/production/.coderabbit.yaml
+# (loaded automatically because the central repo is named `coderabbit`
+# under the same GitHub org as this repo).
+#
+# This file is also propagated to the VyOS-Networks mirror of this repo
+# (`VyOS-Networks/vyos-1x`) by the gen-1 mirror pipeline. CodeRabbit's
+# Atlassian/Jira OAuth grant is attached to the `VyOS-Networks` org only
+# (CodeRabbit allows one GitHub-org → Jira-tenant link per install), so:
+#   - On the vyos source repo (public), `usage: auto` self-disables. No
+#     Jira context is fetched — there's no OAuth grant on this install.
+#   - On the VyOS-Networks mirror, `usage: auto` activates Jira (private
+#     repo + valid OAuth grant) and `project_keys` scopes it to VD.
+#
+# This makes one file the single source of truth across both orgs.
