feat(tracing): collect skill usage events (#6727)
* feat(tracing): collect skill usage events

PR #6652 added SkillUsedEvent but deliberately shipped no listener wiring,
so the event reached no collector. The trace listener subscribed to the five
setup events -- discovery, load, activation, failure -- and none of them can
answer the question skills observability is for: activation is idempotent and
fires once at setup, so an agent using a skill across twenty turns produces
exactly one event.

SkillUsedEvent is the only runtime signal and the only one that re-fires per
execution. Subscribing to it lets a trace attribute skill usage to an agent
and a task.

* fix(tests): scope the trace-listener handlers, assert the forwarded event

CrewAIEventsBus is a singleton, so constructing one in the fixture still
registered against the process-wide bus. _register_action_event_handlers
attached every action handler with no cleanup, leaving them live after the
patch ended -- firing against a listener built with __new__, which has no
batch_manager, in whatever test ran next. scoped_handlers clears them.

Also assert the event object itself is forwarded, not just its type: the
collector serializes the event, so dropping or replacing it would lose every
attribution field while still passing a type-only check.

Both raised in review on #6727.

* test: assert the forwarded skill event by identity

Comparing field values would still pass if a handler forwarded a
reconstructed copy rather than the event itself. Bind the event and assert
`forwarded is event`.

Raised in review on #6727.
