Subject: [PATCH] fix: inject current date into WebSearchTool description

Make WebSearchTool.Description() dynamic so the LLM sees today's date
exactly at the point where it constructs search queries. Previously, the
static description caused the model to default to its training-cutoff
year for time-relative queries (e.g. "yesterday's AI news").

Fixes #754
