- AgentCatalog now records per-definition load errors (bad YAML, unknown
provider/profile/model/tool/skill, or explicit delegate edge to an absent
target) and excludes only the failing definition, never failing gateway
startup or reload; config- and directory-trust-level errors stay fatal
- Explicit delegation to an absent target cascades to deactivate the
delegating agent; `*` and implicit general-purpose delegation do not
- GET /api/agents lists broken definitions with parse/load errors so they
can be fixed and re-enabled from the WebUI instead of disappearing
- WebUI shows an error banner on broken definitions, hides the enable switch,
pre-fills the editor via lenient parsing, and re-enables on save
- Bump version to 1.16.0
