pierrenode 67d4bbb812 fix(state): route session-resume reads through the WAL read-only connection
get_messages_as_conversation, get_resume_conversations, and
get_ancestor_display_prefix still took self._lock — the same global
choke point the read-path split (WAL per-thread read-only connections)
was meant to remove from every recall/browse read. These three are the
hottest reads in the file: every session resume across the gateway,
CLI, and ACP adapter goes through one of them, so a resume racing a
burst of concurrent-session writer flushes still convoys behind them
exactly like the fixed paths used to.

_session_lineage_root_to_tip (the lineage walk shared by all three,
plus get_conversation_root) had its own independent self._lock use and
needed the same conversion — without it the outer functions still
blocked on the very first line.

Verified empirically: a reader thread calling all three functions
while another thread holds self._lock blocked for the writer's full
hold duration before the fix, and returned immediately after (SQLite
3.50.4 in this dev venv falls back to journal_mode=DELETE per the
WAL-reset-bug guard, so the requires_wal-marked regression test is
exercised via a local WAL-forced script instead; it still runs and
passes on any runtime where WAL is actually active).
