When context compression triggers, the SUMMARY_PREFIX instructs the
model to treat the summary as 'background reference, NOT as active
instructions'. This causes the agent to ignore its persistent memory
(MEMORY.md, USER.md) after compaction + session resume, because memory
is part of the system prompt that gets the same demotion.
Changes:
- SUMMARY_PREFIX: Added explicit note that persistent memory is ALWAYS
authoritative and must never be deprioritized by compaction notes.
- System prompt compression note: Added reminder that memory remains
fully authoritative regardless of compaction.
- build_memory_context_block: Changed 'informational background data'
to 'authoritative reference data' to align with memory's actual role.
- _INTERNAL_NOTE_RE: Updated regex to match both old and new wording
(backward compatible with existing sessions).
