* Fix Studio silently exiting on Windows without error output
On Windows, `unsloth studio` launches a child process via
subprocess.Popen to run the server in the studio venv. If the child
crashes (e.g. due to a missing package), the parent just calls
typer.Exit(rc) with no message -- the user sees "Launching Unsloth
Studio... Please wait..." and then the prompt returns with zero
feedback.
Root cause: `data_designer_unstructured_seed` is imported at the top
level in seed.py. If this package is not installed in the studio venv,
the entire import chain (seed.py -> routes/__init__.py -> main.py ->
run_server()) crashes with ModuleNotFoundError. Since run.py has no
try/except around run_server() and studio.py does not report nonzero
exit codes, the failure is completely silent.
Changes:
- run.py: wrap run_server() in try/except, print clear error with
traceback to stderr. Also reconfigure stderr encoding on Windows so
tracebacks with non-ASCII paths do not cause secondary failures.
- studio.py: print an error message when the child process exits with
a nonzero code on Windows, so the user knows something went wrong.
- seed.py: make data_designer_unstructured_seed import optional with
a try/except fallback. The server starts normally and only returns
HTTP 500 if the unstructured seed endpoints are actually called.

* Skip Anaconda/Miniconda Python when creating Studio venv on Windows
Conda-bundled CPython ships modified DLL search paths that prevent
torch from loading c10.dll on Windows. The Studio server fails
silently at startup because the venv was created with conda's Python.
Standalone CPython (python.org, winget, uv) does not have this issue.
Both install.ps1 and setup.ps1 now skip any Python binary whose path
contains conda, miniconda, anaconda, miniforge, or mambaforge when
selecting the interpreter for the studio venv. If only conda Python
is available, the scripts print an error with instructions to install
standalone CPython.
* Fix multi-file preview crash and improve setup.ps1 Python discovery
Addresses review findings [10/10] and [8/10]:
1. seed.py: _read_preview_rows_from_multi_files() had a hard import
of build_multi_file_preview_rows inside the function body, bypassing
the optional-plugin guard. Moved it into the top-level try/except
block and added a None guard matching the other functions.
2. setup.ps1: Python discovery now probes py.exe (Python Launcher)
first, uses Get-Command -All to look past conda entries that shadow
standalone CPython further down PATH, skips WindowsApps stubs, and
resolves the actual executable path so venv creation does not
re-resolve back to a conda interpreter.

* Check sys.base_prefix to catch venvs created from conda Python
A venv created from conda Python (e.g. C:\Users\danie\.venv) has a
path that does not contain "conda", but sys.base_prefix still points
to the conda install (e.g. C:\Users\danie\miniconda3). The previous
path-only check missed this case entirely.
Both install.ps1 and setup.ps1 now use a Test-IsConda helper that
checks both the executable path AND sys.base_prefix against the
conda/miniconda/anaconda/miniforge/mambaforge pattern. This catches:
- Direct conda Python executables
- Venvs created from conda Python (base_prefix reveals the origin)
* Fix install.ps1 passing version string to uv venv instead of resolved path
Find-CompatiblePython returned a bare version string (e.g. "3.13")
which was passed to `uv venv --python 3.13`. uv performs its own
interpreter discovery and can resolve that version string back to a
conda Python, defeating the entire conda-skip logic.
Now Find-CompatiblePython returns a hashtable with both .Version (for
display) and .Path (the resolved absolute executable path). The venv
is created with `uv venv --python <absolute-path>`, ensuring uv uses
the exact interpreter we validated.
* Quote resolved Python path in uv venv call for paths with spaces

* fix(recipe-studio): prevent fitView from zooming to wrong location on recipe load
* feat: add pymupdf/python-docx deps and unstructured uploads storage root
* feat: add POST /seed/upload-unstructured-file endpoint
* feat: add multi-file chunking with source_file column
* feat: update frontend types and API layer for multi-file upload
* feat: round-robin preview rows across source files
Ensures every uploaded file is represented in the preview table
by cycling through sources instead of just taking the first N rows.
* fix: disable OCR, fix auto-load timing, fix persistence on reload
- Disable pymupdf4llm OCR with write_images=False, show_progress=False
- Replace onAllUploaded callback with useEffect that detects uploading→done
transition (avoids stale closure reading empty file IDs)
- Fix importer to preserve file IDs from saved recipes instead of clearing
(clearing only happens at share time via sanitizeSeedForShare)
* fix: harden unstructured upload with input validation and state fixes
Validate block_id/file_id with alphanumeric regex to prevent path
traversal, use exact stem match for file deletion, add error handling
for metadata writes and empty files, fix React stale closures and
object mutations in upload loop, and correct validation logic for
unstructured seed resolved_paths.

* fix: address PR review - legacy path import, share sanitizer, sync effect
Promote legacy source.path into resolved_paths for old unstructured
recipes, clear source.paths in share sanitizer to prevent leaking local
filesystem paths, and gate file sync effect to dialog open transition
so users can actually delete all uploaded files.

* fix(seed): disable remote code execution for seed inspect loads
* fix(test): use __file__-relative path in seed test
The test used a CWD-relative path (`studio/backend/routes/...`) which
only resolved when pytest was invoked from the repo root. Use
`Path(__file__).resolve()` so the test passes regardless of CWD.
