Haile ebb0e59e80 fix: file tree concurrency (#828 )

* perf(file-tree): parallelize directory traversal and widen default ignore list

The project file-tree endpoint walked children sequentially with
`await fsPromises.stat()` inside a for-loop plus a separate
`fsPromises.access()` probe before recursing. On high-latency
filesystems (NFS/SMB) every one of those round-trips was serialized,
so a 120k-file SMB-mounted project took ~2 minutes to load.

This change:
* Runs stat() and recursive getFileTree() calls in parallel via
  `Promise.all` — pipelines round-trips and lets subtree traversals
  overlap.
* Drops the redundant access() probe; any EACCES now surfaces from
  readdir's own try/catch in the recursive call, saving one RTT per
  directory.
* Extracts the hardcoded skip list into an IGNORED_DIRS Set and
  extends it to cover common Python / Rust / JVM / IDE build
  artefacts (.next, __pycache__, .pytest_cache, .tox, .venv,
  target, .gradle, .idea, coverage, etc).

No API shape change; existing consumers get the same tree structure,
only much faster on large or remote-mounted projects.

* fix(file-tree): bound filesystem traversal concurrency

Prevent large file-tree scans from launching unbounded stat and readdir work.

Keep the parallel traversal benefit on high-latency mounts with a bounded queue.

Ignore skipped names only for directories so same-named files stay visible.

* fix(file-tree): inspect entries with lstat

Use lstat for file-tree metadata so symlink entries are identified without following targets.
