Telemetry adapter backed by Foundation.Telemetry.

This is the recommended runtime telemetry adapter. It keeps Pristine on the normal :telemetry handler model while letting callers attach exporters such as TelemetryReporter separately.

This adapter provides full telemetry support including:

• Event emission
• Function timing with automatic duration measurement
• Counter and gauge metrics

Event naming follows a small normalization rule:

• atom shorthand is prefixed as [:pristine, event]
• caller-supplied event paths are emitted unchanged

Usage

# Emit a custom event
Foundation.emit(:request_completed, %{path: "/api"}, %{duration: 100})

# Measure a function
result = Foundation.measure(:database_query, %{table: "users"}, fn ->
  query_database()
end)

# Emit a counter
Foundation.emit_counter(:request_count, %{method: :get})

# Emit a gauge
Foundation.emit_gauge(:queue_size, 42, %{queue: "jobs"})

Event Naming

Examples:

• emit(:request, ...) emits [:pristine, :request]
• measure(:query, ...) emits [:pristine, :query]
• emit([:my_sdk, :request, :stop], ...) emits that exact path
