#2358
Currently, when collecting hotspot-related metrics, the Go collector only adds
new tables. If a large number of tables are deleted, the collector may still retain
those deleted tables in memory, leading to excessive memory usage.
This PR introduces a table cleanup mechanism: if no metric data has been collected
for a table over a prolonged period, the table will be removed to release the memory
it occupies.
