fix(hook): handle error from events.LogFeed (#440)

* fix(beads): cache version check and add timeout to prevent cli lag

* fix(mail_queue): add nil check for queue config

Prevents potential nil pointer panic when queue config exists
in map but has nil value. Added || queueCfg == nil check to
the queue lookup condition in runMailClaim function.

Fixes potential panic that could occur if a queue entry exists
in config but with a nil value.

* fix(migrate_agents_test): fix icon expectations to match actual output

The printMigrationResult function uses icons with two leading spaces
("  ✓", "  ⊘", "  ✗") but the test expected icons without spaces.
This fixes the test expectations to match the actual output format.

* fix(hook): handle error from events.LogFeed

Previously the error from LogFeed was silently ignored with _.
Now we log the error to stderr at warning level but don't fail
the operation since the primary hook action succeeded.
