Nested memory loaded-file tracking removed, and inner calls change how they read files

What

Nested memory files are CLAUDE.md files in subfolders that Claude Code loads when Claude works in those folders. Claude Code used to keep a list of which ones it had already loaded. That list, loadedNestedMemoryPaths, is removed:

• The list and its clean-up step evictNestedMemoryPaths are gone.
• Compaction, which shortens a long conversation by summarising it, no longer clears the list. It still clears readFileState and the memory selector.
• The list is no longer passed from a parent to sub-contexts such as subagents (helper Claudes that work on a side task).

Two related changes affect inner calls, which are calls made inside another operation:

• fileReadingLimits is no longer passed to inner calls.
• For an inner call with no files read yet, dedupUnchangedReads is turned off, so it no longer gets a short "unchanged" answer for a file it never saw.

Why

This changes when nested CLAUDE.md files are brought back into the conversation after compaction or inside subagents. If Claude seems to miss or repeat instructions from a subfolder's CLAUDE.md after a long session, this is the area that changed.
