Release 0.7.0

Cuts the large post-0.6.0 pile as a pinnable release: the machines
rename (ADR-011), the API import surface, personal/scoped/collector
API tokens and the get_permissions plugin hook, the ADR-010 frontend
hook contract, per-plugin migrations, model/employee photos, the
dualpath single-machine toggle and relationship propagation, support
teams, email sending, and the shared asset label generator. Plugin
contract moved 0.6.0 -> 0.10.0 over this range (distinct series per
ADR-007).
