      Remove the chunk cache implementation from WiredTiger.

      Files to delete:

      • src/block_cache/block_chunkcache.c
      • src/conn/conn_chunkcache.c
      • src/include/block_chunkcache.h

      Files to update:

      • src/conn/conn_open.c — remove _wt_chunkcache_setup and _wti_chunkcache_metadata_create calls
      • src/conn/conn_api.c — remove teardown calls and salvage call
      • src/block/block_read.c — remove chunk cache read integration
      • src/conn/conn_tiered.c — remove chunk cache hooks on tiered flush
      • src/conn/conn_handle.c — remove chunk cache fields from WT_CONNECTION_IMPL
      • src/include/connection.hsrc/include/wt_internal.hsrc/include/extern.h — remove declarations
      • dist/filelistdist/filelist.bzl — remove deleted files

      Acceptance criteria: builds pass on all platforms with no compiler warnings. No chunk cache symbols remain.
