changelog: add release notes for v0.20260808.0

[berendt]

Fixes RabbitMQ node address resolution: interface fact keys with
dots (e.g. bond0.100) are preserved, resolution now goes through
Ansible host-context templating and a controller-side action
plugin, and console_interface is honoured as a fallback. Adds a
SONiC config-generation E2E golden test and RabbitMQ integration
tests wired into CI. Bumps sushy, next, eslint-config-next,
gitpython, and huey.

Generated with generate-changelog-input.sh using claude-sonnet-5.

### Comment 1
<location path="CHANGELOG.md" line_range="17" />
<code_context>
+- Add integration tests validating RabbitMQ node interface resolution against real Ansible, wired into CI (osism/python-osism#2577)
+
+### Fixed
+- Rabbitmq node address lookup now keeps dots in interface fact keys instead of mangling them, fixing lookups for VLAN interfaces such as bond0.100 (osism/python-osism#2575)
+- Narrowed the secrets-file existence mock in rabbitmq tests so it no longer interferes with ansible's own file checks (osism/python-osism#2576)
+- Resolve RabbitMQ node internal_interface through Ansible host-context templating instead of a hand-written resolver, correctly handling all Jinja2 expression shapes (osism/python-osism#2578, osism/python-osism@9f78dc2)
</code_context>
