fix: sync bundled skills to default profile when updating from a named profile (#5795)

The filter in cmd_update() excluded is_default profiles from the
cross-profile skill sync loop. When running 'hermes update' from a
named profile (e.g. hermes -p coder update), the default profile
(~/.hermes) never received new bundled skills.

Remove the 'not p.is_default' condition so all profiles — including
default — are synced regardless of which profile runs the update.
