fix(tools): migrate the add_task_scope description on existing databases (F8)

add_task_scope is seeded through BuiltinToolSeeds, SeedTool inserts only
once, and ToolResolve serves the stored row, so existing installs kept the
old "this is the task's authorization boundary" text.

seedTaskScopeDescription runs from seedOrchestrationTools and updates the
description only:

  UPDATE tools SET description=$new, updated_at=now()
  WHERE key='add_task_scope' AND system AND description=$old

$old is the description as seeded at 0dc8bdf, kept verbatim; $new is the
code description from BuiltinToolSeeds. It is idempotent, a no-op when the
row is absent, and leaves an operator-edited description alone. It does not
use RefreshToolDefaults, which overwrites without condition.

TestTaskScopeDescriptionUpgrade (server, PG) covers the replacement, the
preserved custom text, an unchanged updated_at on a second run, and the
description ToolResolve serves to the planner.

 - The goal is a URL or a host-bearing address (e.g. https://xxx.example.com/path, app.example.com) → take its **full hostname**, kind=subdomain, value=full hostname.
   Example: goal https://a1b2c3.lab.example.net/path → kind=subdomain, value=a1b2c3.lab.example.net (**not** example.net).
   **Never** shrink a subdomain-bearing hostname to its root domain — registering all of example.com upon seeing xxx.example.com expands the scope beyond the user's target, violating the minimal-scope principle.
