mark_returned() was append-only without checking if the key already
existed, causing duplicates to accumulate across hook invocations.
load_returned() then returned all entries including duplicates, which
made the returned count exceed the seen count, causing a u64 underflow
in the pre-seeded calculation.
Fix: check load_returned() before appending in mark_returned(), dedup
on read in load_returned(), and use saturating_sub for the pre-seeded
count as a safety net.

Move JsonlBackwardIter and find_last_compaction() from
parse-claude-conversation into a shared transcript module. Both
memory-search and parse-claude-conversation now use the same robust
compaction detection: mmap-based backward scan, JSON parsing to
verify user-type message, content prefix check.
Replaces memory-search's old detect_compaction() which did a forward
scan with raw string matching on "continued from a previous
conversation" — that could false-positive on the string appearing
in assistant output or tool results.
Add parse-claude-conversation as a new binary for debugging what's
in the context window post-compaction.

poc-daemon (notification routing, idle timer, IRC, Telegram) was already
fully self-contained with no imports from the poc-memory library. Now it's
a proper separate crate with its own Cargo.toml and capnp schema.
poc-memory retains the store, graph, search, neuro, knowledge, and the
jobkit-based memory maintenance daemon (daemon.rs).
