  1. fix: prevent FastStream bootstrap NameError when optional extras are … 

    …missing

Two code paths in FastStreamBootstrapper referenced symbols from optional
extras unconditionally, bypassing the check_dependencies skip-with-warning
machinery and raising NameError at bootstrap time when prometheus_client
or opentelemetry was absent (issue #87).

- BaseBootstrapper._register_or_skip now calls check_dependencies on the
  instrument class before instantiation, so an instrument whose __init__
  references gated symbols (e.g. FastStreamPrometheusInstrument's
  collector_registry default_factory) is skipped cleanly.
- FastStreamHealthChecksInstrument.bootstrap guards the tracer reference
  with import_checker.is_opentelemetry_installed so the default
  opentelemetry_generate_health_check_spans=True no longer crashes
  installs without the opentelemetry extra.
- Adds regression tests plus a conftest helper that wipes the bootstrapper
  module's globals before reload, so the conditional-import branches
  re-evaluate against the patched import_checker flags.
