efiten 40c3aa13f9 fix(paths): exclude false-positive paths from short-prefix collisions (#930) ...

Fixes #929

## Summary

- `handleNodePaths` pulls candidates from `byPathHop` using 2-char and
4-char prefix keys (e.g. `"7a"` for a node using 1-byte adverts)
- When two nodes share the same short prefix, paths through the *other*
node are included as candidates
- The `resolved_path` post-filter covers decoded packets but falls
through conservatively (`inIndex = true`) when `resolved_path` is NULL,
letting false positives reach the response

**Fix:** during the aggregation phase (which already calls `resolveHop`
per hop), add a `containsTarget` check. If every hop resolves to a
different node's pubkey, skip the path. Packets confirmed via the
full-pubkey index key or via SQL bypass the check. Unresolvable hops are
kept conservatively.

## Test plan
- [x] `TestHandleNodePaths_PrefixCollisionExclusion`: two nodes sharing
`"7a"` prefix; verifies the path with no `resolved_path` (false
positive) is excluded and the SQL-confirmed path (true positive) is
included
- [x] Full test suite: `go test github.com/corescope/server` — all pass
