Subject: [PATCH] fix(general): do not included concatenated entries in log
 (#5231)

Truncate concatenation debug log to avoid 1M+ char output

Log entry count and total length instead of dumping the entire
concatenatedEntries slice, which could produce 1M+ character JSON
in debug logs.

- Fixes #3093
