Fixes#8214 by removing the '--staged' flag from the undo git restore
command. This ensures that while the working tree is reverted to the
snapshot state, the user's staged changes (index) are preserved,
preventing data loss. Also adds a regression test.
This PR updates ghost snapshotting to avoid capturing oversized
untracked artifacts while keeping undo safe. Snapshot creation now
builds a temporary index from `git status --porcelain=2 -z`, writes a
tree and detached commit without touching refs, and records any ignored
large files/dirs in the snapshot report. Undo uses that metadata to
preserve large local artifacts while still cleaning up new transient
files.
# Ghost snapshot ignores
This PR should close#7067, #7395, #7405.
Prior to this change the ghost snapshot task ran `git status
--ignored=matching` so the report picked up literally every ignored
file. When a directory only contained entries matched by patterns such
as `dozens/*.txt`, `/test123/generated/*.html`, or `/wp-includes/*`, Git
still enumerated them and the large-untracked-dir detection treated the
parent directory as “large,” even though everything inside was
intentionally ignored.
By removing `--ignored=matching` we only capture true untracked paths
now, so those patterns stay out of the snapshot report and no longer
trigger the “large untracked directories” warning.
