Release 9.1.0: Events API, housekeeping

[bartes]

What

Add SDK support for the Events API (enterprise) and clean up unused internal code.

New: Events API

Three new client methods for querying event data sent to Castle:

Method	Endpoint	Description
events_schema	GET /v1/events/schema	Available fields and supported operations
query_events	POST /v1/events/query	Search raw event records
group_events	POST /v1/events/group	Aggregate and group events

client = Castle::Client.from_request(request)

# Fetch the schema
schema = client.events_schema

# Query raw events
results = client.query_events(
  filters: [{ field: 'user.id', op: '$eq', value: 'u-42' }],
  query_type: '$records_with_count'
)

# Aggregate events
groups = client.group_events(
  filters: [{ field: 'user.id', op: '$eq', value: 'u-42' }]
)

Follows the existing layered architecture (Command -> API -> ClientAction) used by Lists and ListItems. Filters and sort parameters are validated client-side.

Housekeeping

• Removed Castle::Validators::NotSupported — dead code, never called
• Inlined HTTPS_SCHEME string comparison in GetConnection — single-use constant
