* fix(javascript): keep both-direction feature traces from crossing shared containers
trace_application_feature with direction "both" walked the application
graph as if it were undirected. From a seed, one outgoing or incoming step
into a shared container (an asset or the artifact root) followed by steps
in the other direction reached every sibling of that container, so a trace
seeded on one storage key returned the whole connected graph.
"both" now returns the union of the outgoing and incoming closures. Each
walk keeps its own predecessor chains, so a terminal path never changes
direction midway. "outgoing" and "incoming" are unchanged.
* test(javascript): check both-direction trace paths end to end
The existing tests checked predecessor maps but no returned path. Add a
trace whose seed reaches one storage terminal outgoing and another
incoming, and assert each path's complete node_ids and edge_ids. A
pathTo that reads only the first walk's map returns a one-node path for
the incoming terminal and fails this test.
* fix(javascript): confine only ascended containers in both-direction traces
Making "both" the union of separate outgoing and incoming walks dropped
modules that a feature reaches by crossing directions. In the Notes
known-answer evaluation, the notes:export channel is pointed at by both
the preload asset (invokes) and the handler (handles); its preload,
renderer and csv modules are reached only through relationships that
change direction, so the trace kept main.js alone and the feature_modules
claim failed in tests/boundary/mcp/agentKnownAnswerMcp.test.ts.
Walk both directions in one traversal again, and confine only the
containment case the change was meant to stop: a node reached by stepping
up a contains edge from one of its children follows only further contains
steps up. A shared asset or artifact root then no longer leads into its
other children, while relationships across the feature are kept. The
Notes trace returns csv.js, main.js, preload.js and renderer.js again
(30 nodes; the previous main returned the whole 32-node graph).
outgoing and incoming traces are unchanged, and paths come from one
predecessor map again, as before this branch.
