Swobu v1.0.0

What changed

Promotes the proven 1.0 release-candidate line to the first stable Swobu
release.
Preserves every authored operator connection fact when Cockpit reads and
edits a target, including DeepSeek file credentials, by using the shared
validated connection decoder instead of a parallel transport-arm switch.
Gives Z.AI an honest open-set model field in Cockpit, replacing the empty
catalog picker with direct model entry while preserving submit and Escape
behavior.
Adds provider-boundary proofs that client-only request fields do not leak
into incompatible target documents: Cline's reasoning.exclude is omitted
for custom OpenAI-compatible Chat requests, and Continue's empty stop list
is omitted for Azure Chat Completions.

None.

None. Existing workspaces, routes, targets, credentials, and provider choices
continue to use their persisted identities.
