Also removes unneeded configurability of the tmux session name
Parallel ws1+ instances were configured by generating a gitignored docker/devenv/instances/wsN.env overlay on every start and layering it over defaults.env with a second --env-file. The file looked editable but was overwritten each run and could go stale; every value in it is a pure function of the instance number.
Replace it with instance-env-overrides, which echoes the per-instance KEY=VALUE pairs that instance-compose injects into its env -i docker compose call. Compose gives shell-env precedence over --env-file, so they override the defaults.env baseline; nothing is written to disk and the values are recomputed every call, so they cannot drift. Re-key the is-it-set-up guard to the workspace clone's existence, drop the unused instances/ dir and its .gitignore entry, and trim the per-instance-config docs and memory to current behaviour.
docker compose config renders byte-identical to the old overlay mechanism for ws0 and ws1.

Add support for running N parallel devenv instances under separate compose
projects sharing Postgres, MinIO, mailer, and LDAP. Each instance has its
own main container, Valkey, source checkout, tmux session, and host port
range offset by 10000 (3449 -> 13449 -> 23449, etc.).
./manage.sh run-devenv-agentic --n-instances N reconciles the running set
to exactly {ws0..ws(N-1)}: missing instances are created (workspace sync
from the live repo via git ls-files + per-instance env-file generation
under docker/devenv/instances/ + detached tmux startup), surplus instances
are stopped highest-first via compose down (never -v), already-running
instances are left untouched. ws0 binds the live repo at PWD; ws1+ are
scratch clones under ~/.penpot/penpot_workspaces/.
Backend workers (enable-backend-worker) are gated on PENPOT_BACKEND_WORKER
in backend/scripts/_env; ws1+ overlays disable them so async-task
notifications stay bound to a single Valkey Pub/Sub instance.
Compose helpers wrap docker compose with env -i so per-instance overlay
--env-file actually overrides defaults.env -- without the strip, the shell
env from sourcing defaults.env at startup would shadow the overlay (Compose
gives shell precedence over --env-file).
Other:
- Drop network aliases (- main, - redis); use container_name for
cross-container DNS so multiple instances on the shared network don't
fight over the same DNS name.
- Pin volume names via name: (PENPOT_*_VOLUME) so volumes survive project
renames; ws0 keeps the pre-existing physical names (penpotdev_*).
- Remove cross-project depends_on from main.yml (postgres/minio-setup now
live in penpotdev-infra); manage.sh ensure-infra-up docker-waits on the
minio-setup one-shot.
- Strict arg parsing in run-devenv / run-devenv-agentic; --n-instances 0
rejected.
- Remove unused Host-matched server block from the Caddyfile.

Move shared services into an infra compose file and keep the main devenv container plus Valkey in a separate compose file driven by defaults.env. Parameterize host-side ports, container names, source path, and runtime env while keeping container-internal ports fixed for same-origin proxying.
Make tmux startup idempotent, add attach-devenv for the live instance, move shared MinIO user setup to infra startup, and let exporter scripts load backend _env.local overrides.
