the held settlement request is released only after reconnect is established.
After release, query pending through er and assert its owner is program::id()

Release settlement during reconnect and assert ER state. settlement.remove() releases the held settlement request only after the reconnect loop completes. The post-settlement owner/data comparison reads base.accounts(pending) only. The later value(er, pending, 900) check validates the account ID, but not the ER-observed owner or full data state. The scenario can therefore pass without proving that the ER observed the ownership transition.
Move settlement.remove() into a reconnect cycle, after the reconnect is established. Then query pending through the ER and assert its owner is program::id() and its data matches the expected settled state.

What changed
Adds
redshift/cache_lifecycle, a private-ER scenario that combines cache eviction and base reconnects with three account lifecycle states: read-only accounts updated on base, delegated accounts modified only on the ER, and accounts waiting for undelegation completion. The ER runs with a 256-entry account cache; reads of 512 extra accounts force evictions, base WebSockets are closed once per read-only account, each resubscription is held while a new subscription registers, and delayed older observations are released only after newer state was observed through another channel. Warmed traffic keeps writing a delegated account for the whole sequence. Registered in the catalog as PrivateEr with the redline fixture, in the nextest private-er group, and in the README.Closes #116
Impact
Test-only. Adds one private-ER scenario of about two minutes to the redshift family.
Reviewer notes
The stalled undelegation is released only after the reconnect cycles, so completion is proven after reconnects, not during one. Traffic tolerates a
ProgramAccountNotFoundfailure on the assumption that the small cache may transiently evict the program; progress counts only successful execution Jump to bottom (ctrl+End) ↓ R still fails.
