disktree's visual language is useful in a terminal, especially over SSH. This adds disktree-tui as a local terminal view of disktree-core: the same walk, treemap layout, measurements, findings, removal guards, and agent handoff, with no GUI crate in the terminal package. Run it inside an SSH session to inspect that machine.

• At 120 columns it shows the mosaic, inspector, findings, and free-space bar; around 80 it keeps the map, and around 45 it becomes a list. Long paths marquee while the surrounding chrome stays still.
• Omarchy theme following is optional and falls back cleanly when undetected. Native Linux links only libc and libgcc; the musl target builds a static binary. Windows is supported; macOS is wired into CI but has not been tested interactively.
• The optional core tui feature retains metadata for changing Size/Files/Age, Hidden, and Disk/Apparent without another walk once hidden entries are loaded. A GUI-only build keeps the 88-byte Node. Free-space projections use the core's volume attribution.
• cargo xtask lint and cargo xtask test pass locally, as do default core tests, Windows/macOS target checks, and native/static Linux release builds. CI covers Linux, macOS, Windows, and additional architectures.

All three use assets/tui/fixture.tar.gz, captured with animations paused. To try the fixture:

mkdir -p /tmp/disktree-fixture
tar -xzf assets/tui/fixture.tar.gz -C /tmp/disktree-fixture --strip-components=1
cargo run --release --locked -p disktree-tui -- --apparent-size /tmp/disktree-fixture

A separate commit fixes core filtering of nested empty directory matches, with core and TUI regression tests, so those results remain reachable in the list.

PR #32 also touches core findings and the README. A shared GUI/TUI view model could follow as a separate change, if considered.
