feat(config): Add fetchResourceEvents config flag with --no-events CLI override

Adds a new boolean field to SyncConfig that controls whether resource
event fetching is performed during sync:

- SyncConfig.fetch_resource_events: defaults to true via serde
  default_true helper, serialized as "fetchResourceEvents" in JSON
- SyncArgs.no_events: --no-events CLI flag that overrides the config
  value to false when present
- SyncOptions.no_events: propagates the flag through the sync pipeline
- handle_sync_cmd: mutates loaded config when --no-events is set,
  ensuring the flag takes effect regardless of config file contents

This follows the existing pattern established by --no-embed and
--no-docs flags, where CLI flags override config file defaults.
The config is loaded as mutable specifically to support this override.

Also adds "events" to the count command's entity type value_parser,
enabling `lore count events` (implementation in a separate commit).
