Introduce src/hooks.rs as a types-only module (HookDef, HooksMap) and
plumb hooks:/global_hooks: config fields through every scope:
- Config + AppConfig hooks field, both Default impls, the manual
from_config copy, and a COYOTE_HOOKS env override
- Role frontmatter: hand-parsed hooks arm, private field, getter, and
JSON-inline re-serialization in Role::export (malformed maps degrade
to None)
- AgentConfig + Graph: hooks + global_hooks on both structs, copied in
AgentConfig::from_graph, with a per-agent global_hooks env override
- paths::hooks_dir() = <config_dir>/hooks with COYOTE_HOOKS_DIR override
- Commented hooks: block in the global config template (global scope
only; no global_hooks key)
No engine or dispatch logic yet; existing configs parse unchanged.
