resolveGlobs crashes on .quarto/ session temp files (race condition, Windows + Positron)

Bug

Quarto's resolveGlobs → expandGlobSync → walkSync scans the .quarto/ internal
folder and crashes when it encounters a session temp file that was deleted between the
directory listing and the stat call.

Error

ERROR: NotFound: The system cannot find the file specified. (os error 2):
stat 'D:...quarto\quarto-session-temp851f9d1b786c0286'

at Object.statSync (ext:deno_fs/30_fs.js:415:3)
at createWalkEntrySync (quarto.js:2821)
at walkSync (quarto.js:2948)
at expandGlobSync (quarto.js:3092)
at resolveGlobs (quarto.js:8145)

Behaviour

• Error is triggered by Positron IDE's background project scanner, not by quarto render
• quarto render <file> from terminal works without error
• .quartoignore with .quarto/ does not fix it
• Explicit render: list in _quarto.yaml does not fix it

Root cause

.quarto/ is not excluded from the project glob walk. It should be auto-excluded like
.git/, since it is Quarto's own internal directory. Additionally, the NotFound error
from stat should be caught and skipped rather than crashing.

Environment

• Quarto 1.9.36
• Windows 11 (10.0.26200)
• Positron IDE

Start at resolveGlobs and follow its expandGlobSync and walkSync calls, using the reported stack trace to locate the glob-walking implementation. Verify how internal directories and stat failures are handled, then confirm that .quarto/ is skipped and a deleted session temp file no longer crashes the walk.
