概览

Records selectors that should be marked as used by the Lynx CSS rule usage tracker.

Name	Type	Required	Description
`selector`	`array`	No	Selector strings to add to the current CSS rule usage set while CSS rule usage tracking is active.
`selector[]`	`string`	Yes	Selector text. The native handler stores the string as-is and later searches for it in the generated stylesheet text.

Dispatches through LynxDevToolMediator to InspectorTasmExecutor on the TASM thread.
This method is only effective after CSS.startRuleUsageTracking has enabled rule usage tracking.
The handler inserts each params.selector item into an in-memory selector set and does not send a CDP response.
CSS.stopRuleUsageTracking later emits the collected selectors as ruleUsage entries. Each entry contains styleSheetId, startOffset, endOffset, and used.
When CSS.stopRuleUsageTracking runs with no selectors collected by this method, Lynx falls back to collecting id and class selector usage from the DOM tree.
