URL: https://github.com/apache/nuttx/pull/21028
## Summary
Initialize the scheduler task list descriptor table at compile time and
mark it as `const`, instead of filling it during boot with a runtime
initialization helper.
The table only contains static metadata for each task state, including
the associated task queue pointer or wait-object offset and the task list
attribute flags. These descriptor fields are not modified after startup,
so they can safely live in read-only storage.
The actual task queues referenced by the table remain mutable, so task
insertion, removal, blocking, waking, and scheduling behavior are
unchanged.
## Benefits
- Reduces mutable RAM usage by moving static scheduler metadata from
writable data to read-only storage.
- Removes boot-time initialization code for the task list descriptor
table.
- Preserves existing scheduler semantics because only the descriptor
table is made read-only, not the underlying queues.
