feat(convergence/u3): kei-provision Rust crate — unify hetzner+vultr provisioners
Pre-unlock wave U3 (highest-ROI). Task 7 from CONVERGENCE-PLAN —
consolidate 2 provision-*.sh scripts into Rust via Backend trait.
Old shells (provision-hetzner.sh, provision-vultr.sh) had identical
6-subcommand surface (create|status|destroy|list), log/die/check_deps
helpers, idempotency contract. Sole delta: hcloud vs vultr-cli. RULE 0.2
says Rust-first when >50 LOC + growth expected.
New crate _primitives/_rust/kei-provision/:
- src/backend.rs (58 LOC) — Backend trait: create/status/destroy/list;
CreateOpts and ServerInfo structs
- src/backends/hetzner.rs (143 LOC) — shells to `hcloud server ...`
--output=json, parses JSON response, honors HCLOUD_TOKEN env (RULE 0.8)
- src/backends/vultr.rs (189 LOC) — same pattern, `vultr-cli instance`,
honors VULTR_API_KEY env
- src/exec.rs (100 LOC) — Command runner + PATH-aware env preservation
- src/b64.rs (49 LOC) — minimal user-data base64 encoder; zero
transitive deps
- src/main.rs (141 LOC) — clap CLI `kei-provision <backend> <cmd>`
- tests/backend_smoke.rs (184 LOC) — tempdir PATH-inject fake hcloud +
fake vultr-cli, no real cloud. Mutex-serialized (Rust test parallelism).
Tests: 11/11 (3 b64 unit + 8 backend_smoke integration). Coverage:
hetzner status present/absent/list, vultr status found/absent/destroy
idempotent, unknown-backend error, CreateOpts default.
Old shells kept with superseded-v0.17 header — install.sh still copies
them, legacy scripts still work. New users get kei-provision binary.
harden-base.sh untouched (different lifecycle — runs on target VPS).
Backend trait factored to accept aws/doctl/linode follow-ups without
re-architecture.
Workspace Cargo.toml: +kei-provision member (1 line).
