Gud Boi cec6cc2a56 Add `acli.reap`, namespace `tractor_diag` cmds 
Group all xontrib aliases under an `acli.` prefix
so xonsh prefix-completion treats them as a sub-cmd
group — `acli.<TAB>` lists the full set. No parent
`acli` cmd exists; the dot is purely naming.

Renames (incl `-` -> `_` in suffixes for shell-
identifier-friendliness):

  - `pytree`         -> `acli.pytree`
  - `hung-dump`      -> `acli.hung_dump`
  - `bindspace-scan` -> `acli.bindspace_scan`

Add new `acli.reap` wrapping `scripts/tractor-reap`:

Deats,
- 3 opt-in phases via flags:

  1. process reap — `find_orphans()` (default,
     PPid=1 + cwd=repo + cmdline `python`) or
     `find_descendants(--parent PID)`. SIGINT
     first, SIGKILL after `--grace` (def 3.0s).

  2. `/dev/shm` sweep (`--shm`/`--shm-only`) —
     `find_orphaned_shm()` + `reap_shm()`. needed
     bc `tractor` disables `mp.resource_tracker`.

  3. UDS sock-file sweep (`--uds`/`--uds-only`) —
     `find_orphaned_uds()` + `reap_uds()` for stale
     `${XDG_RUNTIME_DIR}/tractor/<name>@<pid>.sock`
     entries. See #452.

- `--dry-run` lists matches without signalling/
  unlinking; survivor pids or sweep errors flip
  the alias rc to `1`.
- lazy-imports `tractor._testing._reap` after
  `git rev-parse --show-toplevel` (with
  `Path(__file__).parent.parent` fallback) so the
  contrib is loadable before the venv is on
  `sys.path`.
- `argparse.SystemExit` on `-h`/bad-args is
  caught + returned as the alias rc instead of
  killing xonsh.

Gud Boi 0f4e671862 Add `--tree` flag and cross-bucket parent annos to `pytree` 
Extend `pytree` with two usability improvements:

- `--tree`/`-t` opt-in flag emits a flat walk-order `## tree` section at
  the top preserving contiguous parent-child shape (no
  severity-grouping), so the full tree structure is visible without
  cross-ref'ing between severity buckets.

- Cross-bucket parent annotation: when a row's parent (by ppid) lives in
  a *different* severity bucket, suffix with `[parent: <pid> (in
  `<bucket>`)]` so the `└─` marker resolves even when bucketing scatters
  parent/child into separate sections.

Also,
- split arg parsing into flag vs positional args.
- add `pid_to_bucket` dict + `walk_order` list to back both features
- rename inner `ppid` shadow to `ppid_str` to avoid collision with the
  outer `ppid` variable.

Gud Boi 7b14fdcd96 Add `tractor_diag`(nosis) xontrib with aliases 
Xonsh xontrib providing three diagnostic commands
for tractor development / hang investigation:

- `pytree <pid|pat>` — psutil-backed proc tree with severity-bucketed
  output (zombies > orphans > live), tree-depth markers, zombie-safe
  rendering.
- `hung-dump <pid|pat>` — kernel `wchan`/`stack` + `py-spy dump
  --locals` per descendant, sudo-cred caching upfront, pgrep fallback
  when psutil absent.
- `bindspace-scan [<dir>]` — scan UDS bindspace for orphaned
  `<name>@<pid>.sock` files whose binder pid is dead, emit `rm`
  one-liner for cleanup.
