wernerhp cc84af9fad fix(memory): preserve genuine pre-delimiter content in merged compaction rows
teknium1 review on #57690: harvesting logic was skipping the ENTIRE merged
row when a compaction summary was appended to the tail message, discarding
real prior user content that context_compressor retains before the
_MERGED_SUMMARY_DELIMITER. Extract and harvest that pre-delimiter segment
instead of dropping it wholesale.

Revert-to-fail: reverting plugins/memory/holographic/__init__.py alone
drops test_merged_into_tail_preserves_genuine_pre_delimiter_preference
(19 passed, 1 failed); restoring the fix returns 20/20 passed.

"""Regression tests for #57682 — holographic auto_extract harvested
context-compaction handoff summaries into fact_store, and ran even when
configured off.
Two compounding defects:
1. Gate: the plugin's config schema declares ``auto_extract`` as a string enum
(``"false"``/``"true"``), and the ``on_session_end`` gate used plain
truthiness — ``not "false"`` is ``False`` — so extraction ran despite being
explicitly configured off.
2. Eligibility: ``_auto_extract_facts`` scanned every ``role == "user"``
message. Compaction handoff summaries can be inserted as ``role="user"``
messages, and their prose reliably matches the decision patterns
(``we decided/agreed/chose``, ``the project uses/needs/requires``), so the
compactor's own output was stored as a durable ``project`` fact on every
session rollover that followed a compaction.
