learn: trace-enabled Joern run over labelled units (opt-in trace in taint.sc, trace parsing, resumable runner)
Implemented with Codex. Default scan queries do not request a trace. Co-Authored-By: Claude Opus 5.5 <[email protected]>

"""Resumable, serial, labelled-function Joern traces. No network or live-source mounts.
|
||||
|
||||
Pair pins are excerpt blob identities, NOT commits: materialize their catalog side
|
||||
and registration documents. Repository pins are exported from existing local clones.
|
||||
The analyzer is git archive HEAD src plus a hashed snapshot of this uncommitted tool's
|
||||
four implementation files; this allows review/worktree use without making a commit.
