agents: in-flight node exclusion prevents concurrent collisions

Track which nodes are being processed across all concurrent agents.
When an agent claims seeds, it adds them and their strongly-connected
neighbors (score = link_strength * node_weight > 0.15) to a shared
HashSet. Concurrent agents filter these out when running their query,
ensuring they work on distant parts of the graph.

This replaces the eager-visit approach with a proper scheduling
mechanism: the daemon serializes seed selection while parallelizing
LLM work. The in-flight set is released on completion (or error).

Previously: core-personality rewritten 12x, irc-regulars 10x, same
node superseded 12x — concurrent agents all selected the same
high-degree hub nodes. Now they'll spread across the graph.
