TailMessages is a proper iterator that yields (role, text, timestamp)
newest-first. Owns the mmap internally. Caller decides when to stop.
resolve_conversation collects up to 200KB, then reverses to
chronological order. No compaction check needed — the byte budget
naturally limits how far back we scan.

Replaces byte-by-byte backward iteration with memrchr3('{', '}', '"')
which uses SIMD to jump between structurally significant bytes. Major
speedup on large transcripts (1.4GB+).
Also simplifies tail_messages to use a byte budget (200KB) instead
of token counting.

Was parsing every object twice (compaction check + message extract)
and running contains_bytes on every object for the compaction marker.
Now: quick byte pre-filter for "user"/"assistant", parse once, check
compaction after text extraction.

Reverse-scans the mmap'd transcript using JsonlBackwardIter,
collecting user/assistant messages up to a token budget, stopping
at the compaction boundary. Returns messages in chronological order.
resolve_conversation() now uses this instead of parsing the entire
file through extract_conversation + split_on_compaction.

- Agent identity injection: prepend core-personality to all agent prompts
so agents dream as me, not as generic graph workers. Include instructions
to walk the graph and connect new nodes to core concepts.
- Parallel agent scheduling: sequential within type, parallel across types.
Different agent types (linker, organize, replay) run concurrently.
- Linker prompt: graph walking instead of keyword search for connections.
"Explore the local topology and walk the graph until you find the best
connections."
- memory-search fixes: format_results no longer truncates to 5 results,
pipeline default raised to 50, returned file cleared on compaction,
--seen and --seen-full merged, compaction timestamp in --seen output,
max_entries=3 per prompt for steady memory drip.
- Stemmer optimization: strip_suffix now works in-place on a single String
buffer instead of allocating 18 new Strings per word. Note for future:
reversed-suffix trie for O(suffix_len) instead of O(n_rules).
- Transcript: add compaction_timestamp() for --seen display.
- Agent budget configurable (default 4000 from config).

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.
