87748329c8 refactor: move transforms/ into infrahub/ and update all paths (#20)
Move transforms/{queries,templates,tests} under infrahub/transforms/ so all
Infrahub-managed content lives under the dedicated infrahub/ directory,
consistent with schemas/, objects/, and menus/.

Updated paths:
- .infrahub.yml: file_path and template_path entries now prefixed with
  infrahub/transforms/
- infrahub/transforms/tests/*/test.yml: directory references updated from
  transforms/tests/* to infrahub/transforms/tests/*

a492aa3c39 fix: rewrite transform tests to use correct Infrahub pytest format (#20)
Rewrite all three test.yml files to use the Infrahub SDK pytest format
(version: "1.0" / infrahub_tests) instead of the previous invalid
apiVersion/kind schema. Each test file now declares a smoke_check test
(jinja2-transform-smoke) and a unit render test (jinja2-transform-unit-render)
pointing to the local input/output JSON fixtures.

Update output.json files with the actual render output from the fixed templates:
- vlan_yang: trunk_groups is null (not []) for VLANs with no trunk groups set;
  key order reflects Python dict / tojson serialization order.
- interface_yang: corrected MLAG peer-link SVI IP (10.0.199.254/31), added
  iBGP SVI IP (10.0.3.0/31), removed stale Loopback1 IP address.
- vxlan_yang: source_address now includes /32 prefix as stored in Infrahub
  IPHost fields; key order matches tojson output.

Update input.json files to be consistent with the expected output:
- vlan_yang/input.json: trunk_groups.value set to null for VLAN 40.
- interface_yang/input.json: Loopback1 ip_addresses cleared; Vlan4090 IP
  updated to 10.0.199.254/31; Vlan4091 IP added as 10.0.3.0/31.
- vxlan_yang/input.json: source_address updated to 10.0.255.11/32.

a415de85bd fix: use Jinja2 none instead of null and add defensive checks for optional relationships (#20)
Replace all `null` literals with `none` (valid Jinja2/Python) in all three
templates. Add explicit `is defined and is not none and .node is not none`
guards before accessing nested nodes on optional GraphQL relationships, to
avoid `Undefined is not JSON serializable` errors at render time.

Also add `| default(none)` on optional scalar attributes (speed, mode,
lacp_mode, mlag_id, mtu, description, virtual_router_address,
route_distinguisher, learn_restrict, vlan_type, trunk_groups) so that
Infrahub `Undefined` values from unset optional fields are safely coerced
to JSON null rather than crashing tojson serialization.

584a4ad5a4 feat: Add Infrahub Jinja2 transforms for VLANs, interfaces, and VXLAN (#20)
Add three GraphQL queries, Jinja2 templates, and integration tests for
generating YANG-style JSON configuration payloads from Infrahub intent data,
suitable for gNMI Set operations on Arista EOS devices.

Queries (transforms/queries/):
- vlan_intent.gql: Fetches VLANs for a device via VTEP mappings and SVI
  interfaces, including VNI associations.
- interface_intent.gql: Fetches all interface types (loopback, ethernet, vlan,
  lag) with IP addresses and type-specific attributes.
- vxlan_intent.gql: Fetches VTEP config, VLAN-to-VNI mappings, and VRF-to-VNI
  mappings (L3VNI) via VRF device assignments.

Templates (transforms/templates/):
- vlan_yang.j2: Merges VLANs from both VTEP and SVI sources, deduplicates by
  vlan_id, and emits a sorted JSON array.
- interface_yang.j2: Emits a JSON array of interfaces sorted by name, with a
  "type" discriminator field for each interface kind.
- vxlan_yang.j2: Emits a JSON object with vtep config, vlan_vni_mappings, and
  vrf_vni_mappings sections.

Integration tests (transforms/tests/):
- One test directory per transform with input.json (sample GraphQL response for
  leaf1), output.json (expected result), and test.yml config.
- Test data reflects the lab topology: leaf1 VTEP 10.0.255.11, VLAN 40 / VNI
  110040, MLAG VLANs 4090/4091, underlay Ethernet11/12.

.infrahub.yml updated with queries and jinja2_transforms sections.
