LLMs sometimes wrap agent names in backslashes, quotes, or slashes
(e.g. \hephaestus\ instead of hephaestus). The trim() call only
removed whitespace, causing "Agent not found" errors during delegation.
Now strips leading/trailing backslashes, quotes, and slashes before
the case-insensitive agent lookup.
Adds regression tests for backslash-wrapped, double-quoted, and
single-quoted agent names.
Fixes: release blocker — delegate_task to hephaestus failing in
pre-publish review sessions.
