* fix(dev): create backend/sandbox before uvicorn reload-exclude (#3459)
#3426 switched the dev gateway's --reload-exclude patterns to absolute
paths. uvicorn only excludes an absolute path directly when it already
exists as a directory; otherwise it globs the pattern, and Python 3.12's
pathlib raises NotImplementedError("Non-relative patterns are unsupported")
for an absolute glob pattern. serve.sh mkdir'd the .deer-flow excludes but
not backend/sandbox, so `make dev` crashed on startup on a fresh checkout
under Python 3.12 (#3454). docker/dev-entrypoint.sh had the same latent gap.
Create backend/sandbox in both launchers so every absolute exclude stays on
uvicorn's is_dir() short-circuit. Add a regression test that pins the uvicorn
mechanism (crash on missing dir, safe once created) and enforces that every
absolute --reload-exclude is mkdir'd before launch.
Closes#3459
* test(dev): harden reload-exclude invariant parser against false pass/negatives
The launcher invariant test parsed shell with a "mkdir -p" line filter and a
substring membership check. Two latent gaps (sub-threshold for this fix, but
this code guards a user-facing startup path, so close them):
- A `\`-continued multi-line `mkdir` would drop arguments on continuation
lines, silently weakening coverage.
- Substring membership could false-pass when an exclude is a path-prefix of a
different created dir (e.g. `/app/backend/sandbox` "found" inside
`/app/backend/sandbox-other`).
Fold line-continuations, drop comments, and shlex-tokenize each `mkdir`
argument list into an exact set (quotes stripped, `$VAR` literal); assert exact
set membership. Same shlex handling for `--reload-exclude` values. Verified the
parser still flags the pre-fix missing `backend/sandbox` (RED preserved) and no
longer false-passes on a path-prefix.
* fix(dev): gitignore backend/sandbox runtime dir + pin mkdir-before-launch
Address two review findings on the #3459 fix:
- backend/sandbox was described as "gitignored runtime state" but no ignore
rule actually matched it. Add an anchored `/sandbox/` to backend/.gitignore
(anchored so it does NOT shadow the source package
backend/packages/harness/deerflow/sandbox/) so sandbox artifacts created at
runtime can't pollute the working tree or be committed by accident. New test
asserts content under backend/sandbox is ignored, making the claim verifiable.
- The launcher invariant test only proved the sandbox mkdir exists somewhere,
not that it runs before uvicorn starts. Add an order test (sandbox mkdir line
must precede the `uv run uvicorn` launch) so a future edit can't move the
mkdir below the launch and silently reintroduce the crash.

* test(dev): fix reload-exclude parser to handle serve.sh's quoted flag bundle
The previous autofix tokenized each whole line with shlex, but serve.sh packs
every flag into a single double-quoted `GATEWAY_EXTRA_FLAGS="..."` assignment.
shlex collapses that into one token, so no `--reload-exclude` flag is found and
`test_launcher_precreates_every_absolute_reload_exclude[scripts/serve.sh]`
failed CI with "expected at least one absolute reload-exclude".
Parse `--reload-exclude` with a regex that matches a balanced single/double
quoted group or a bare token, so the assignment's surrounding `"` is never
swallowed into the value. This recovers all three serve.sh excludes (the prior
regex also silently dropped the last `$BACKEND_RUNTIME_HOME` because the
adjacent closing quote broke shlex) while still covering dev-entrypoint.sh and
the space-separated `--reload-exclude <value>` form.
