v1.29.0: jump host is core + fix fresh-install setup.sh abort (#125)

Two fresh-install fixes and promote the SSH jump host from opt-in to core.

setup.sh: fix silent abort after "Minting per-app OpenBao tokens". env_get's
grep|cut pipeline returns non-zero under set -euo pipefail when .env exists
(created by the root VAULT_TOKEN env_upsert) but an app-token key is absent
(the normal first-run state); the unguarded existing assignment from env_get
then tripped set -e and killed the script before minting any token. env_get
now always returns 0 (|| true). Reproduced + verified under the exact condition.

jump host is no longer optional:
- docker-compose.yml: drop profiles jump-host from the jump-host service
  (always started); rename the opt-in test fixture profile jump-host to ldap-test.
- setup.sh: SUBMODULES always includes jump-host; build/start/register/summary
  no longer guarded by JUMP_ENABLED; drop the COMPOSE_PROFILES export.
- bootstrap.js: jump provisioning + directory record run unconditionally.
- setup.env.example/docs: drop optional/CFG_JUMP_HOST_ENABLED wording.
