Add community_isolation() to Graph — computes per-community ratio of
internal vs total edge weight. 1.0 = fully isolated, 0.0 = all edges
external.
New query: sort:isolation — sorts nodes by their community's isolation
score, most isolated first. Useful for aiming organize agents at
poorly-integrated knowledge clusters.
New CLI: poc-memory graph communities [N] [--min-size M] — lists
communities sorted by isolation with member preview. Reveals islands
like the Shannon theory cluster (3 nodes, 100% isolated, 0 cross-edges)
and large agent-journal clusters (20-30 nodes, 95% isolated).

Edition 2024 changes:
- gen is reserved: rename variable in query/engine.rs
- set_var is unsafe: wrap in unsafe block in cli/agent.rs
- match ergonomics: add explicit & in spectral.rs filter closure
New --local flag for `poc-memory agent run` bypasses the daemon and
runs the agent directly in-process. Useful for testing agent prompt
changes without waiting in the daemon queue.

calibrate.agent: Haiku-based agent that reads a node and all its
neighbors, then assigns appropriate link strengths relative to each
other. Designed for high-volume runs across the whole graph.
graph link-set: Set strength of an existing link (0.0-1.0).
dominating-set query stage: Greedy 3-covering dominating set — finds
the minimum set of nodes such that every node in the input is within
1 hop of at least 3 selected nodes. Use with calibrate agent to
ensure every link gets assessed from multiple perspectives.
Usage: poc-memory query "content ~ 'bcachefs' | dominating-set"
- 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).

search.rs → query/engine.rs (algorithms, pipeline, seed matching)
query.rs → query/parser.rs (PEG query language, field resolution)
query/mod.rs re-exports for backwards compatibility.
crate::search still works (aliased to query::engine).
crate::query::run_query resolves to the parser's entry point.
No logic changes — pure file reorganization.
