   A potential improvement for v1 archived timeline:
   
   The latest PR already performs a start-instant-based archive lookup:
   
   ```java
   metaClient.getArchivedTimeline(startInstant, false)
   ```
   
   For V1, the missing improvement is to make that the actual incremental-query 
path, not just the candidate-discovery path. Currently:
   
   1. `CompletionTimeQueryViewV1` loads archived instants from the requested 
start time.
   2. `IncrementalQueryAnalyzer` discards that timeline and loads it again.
   
   A cleaner V1 design would have `IncrementalQueryAnalyzer` load the filtered 
archived timeline once, apply `InstantRange` directly to 
`HoodieInstant.requestedTime()`, and reuse that same timeline in 
`QueryContext`. This is valid because V1 has:
   
   ```text
   completion time == requested/start instant time
   ```
   
   That would preserve V2-compatible range semantics while eliminating the 
redundant archive scan. Simply adding another start-time lookup inside 
`CompletionTimeQueryViewV1` would not address the concern—the PR already has 
that part.
