memory_search is now spreading activation — the natural way to search
a graph. Give it seed node keys and it finds conceptually related nodes.
The old keyword-based memory_search and memory_search_content are
removed; memory_query can do everything they did.
Simpler tool set, better defaults. Agents don't need to be told "use
spread not search" — search IS spread now.

The new tool definitions broke surface-observe because they had no
corresponding dispatch handlers — the agent runner saw unknown tools
and ran with no tools at all.

Add `poc-memory graph spread` command that takes multiple seed node keys,
runs spreading activation through the graph, and returns nodes ranked by
total activation — nodes that bridge multiple seed concepts score highest.
Expose spreading_activation() as pub from the query engine. Add
memory_spread and memory_search_content tool definitions for MCP.

New src/thought/ module containing tools and infrastructure shared
between poc-agent and subconscious agents: memory operations, file
tools, bash, context window management.
Currently coexists with agent/tools/ — next step is to wire up both
agent/ and subconscious/ to use thought::dispatch instead of
duplicating the routing logic.
Move dbglog macro to lib.rs so it's available crate-wide regardless
of module compilation order.
