fix: [nomad-step-2] S2.2 — Fix KV v2 overwrite for incremental updates and secure jq interpolation (#880)

Review feedback from PR #895 round 1:

- lib/AGENTS.md (hvault.sh row): add hvault_get_or_empty(PATH) to the
  public-function list; replace the "not sourced at runtime yet" note
  with the three actual callers (vault-apply-policies.sh,
  vault-apply-roles.sh, vault-nomad-auth.sh).
- lib/AGENTS.md (lib/init/nomad/ row): add a one-line description of
  vault-nomad-auth.sh (Step 2, this PR); relabel the row header from
  "Step 0 installer scripts" to "installer scripts" since it now spans
  Step 0 + Step 2.
- lib/init/nomad/vault-nomad-auth.sh: drop the `vault` CLI from the
  binary precondition check — hvault.sh's helpers are all curl-based,
  so the CLI is never invoked. The precondition would spuriously die on
  a Nomad-client-only node that has Vault server reachable but no
  `vault` binary installed. Inline comment preserves the rationale.

+# lib/init/nomad/vault-nomad-auth.sh — Idempotent Vault JWT auth + Nomad wiring
+#
+# Part of the Nomad+Vault migration (S2.3, issue #881). Enables Vault's JWT
+# auth method at path `jwt-nomad`, points it at Nomad's workload-identity
+# JWKS endpoint, writes one role per policy (via tools/vault-apply-roles.sh),
+# updates /etc/nomad.d/server.hcl with the vault stanza, and signals nomad
+# to reload so jobs can exchange short-lived workload-identity tokens for
+# Vault tokens — no shared VAULT_TOKEN in job env.
+#
+# Steps:
+#   1. Enable auth method           (sys/auth/jwt-nomad, type=jwt)
+#   2. Configure JWKS + algs        (auth/jwt-nomad/config)
+#   3. Upsert roles from vault/roles.yaml (delegates to vault-apply-roles.sh)
+#   4. Install /etc/nomad.d/server.hcl from repo + SIGHUP nomad if changed
+#
+# Idempotency contract:
+#   - Auth path already enabled → skip create, log "jwt-nomad already enabled".
+#   - Config identical to desired → skip write, log "jwt-nomad config unchanged".
+#   - Roles: see tools/vault-apply-roles.sh header for per-role diffing.
+#   - server.hcl on disk byte-identical to repo copy → skip write, skip SIGHUP.
+#   - Second run on a fully-configured box is a silent no-op end-to-end.
+#
+# Preconditions:
+#   - S0 complete (empty cluster up: nomad + vault reachable, vault unsealed).
+#   - S2.1 complete: vault/policies/*.hcl applied via tools/vault-apply-policies.sh
+#     (otherwise the roles we write will reference policies Vault does not
+#     know about — the write succeeds, but token minting will fail later).
+#   - Running as root (writes /etc/nomad.d/server.hcl + signals nomad).
+#
+# Environment:
+#   VAULT_ADDR  — default http://127.0.0.1:8200 (matches nomad/vault.hcl).
+#   VAULT_TOKEN — env OR /etc/vault.d/root.token (resolved by lib/hvault.sh).
+#
+# Usage:

+# vault/roles.yaml and upserts each entry as a Vault role under
+# auth/jwt-nomad/role/<name>.
+#
+# Idempotency contract:
+#   For each role entry in vault/roles.yaml:

+#     - Role present, fields match  → skip,  log "role <NAME> unchanged"
+#     - Role present, fields differ → write, log "role <NAME> updated"
+#
+#   Comparison is per-field on the data the CLI would read back
+#   (GET auth/jwt-nomad/role/<NAME>.data.{policies,bound_audiences,
+#   bound_claims,token_ttl,token_max_ttl,token_type}). Only the fields
+#   this script owns are compared — a future field added by hand in
+#   Vault would not be reverted on the next run.

+#
+# Reads existing .env and sops-encrypted .env.vault.enc from the old docker stack

+#
+# Usage:

+## JWT-auth roles (S2.3)
+
+Policies are inert until a Vault token carrying them is minted. In this
+migration that mint path is JWT auth — Nomad jobs exchange their
+workload-identity JWT for a Vault token via
+`auth/jwt-nomad/role/<name>` → `token_policies = ["<policy>"]`. The
+role bindings live in [`../roles.yaml`](../roles.yaml); the script that
+enables the auth method + writes the config + applies roles is
+[`lib/init/nomad/vault-nomad-auth.sh`](../../lib/init/nomad/vault-nomad-auth.sh).
+The applier is [`tools/vault-apply-roles.sh`](../../tools/vault-apply-roles.sh).
+
+### Role → policy naming convention
+
+Role name == policy name, 1:1. `vault/roles.yaml` carries one entry per
+`vault/policies/*.hcl` file:
+
+```yaml
+roles:
+  - name:      service-forgejo      # Vault role
+    policy:    service-forgejo      # ACL policy attached to minted tokens
+    namespace: default              # bound_claims.nomad_namespace
+    job_id:    forgejo              # bound_claims.nomad_job_id
+```
+
+The role name is what jobspecs reference via `vault { role = "..." }` —
+keep it identical to the policy basename so an S2.1↔S2.3 drift (new
+policy without a role, or vice versa) shows up in one directory review,
+not as a runtime "permission denied" at job placement.
+
+`bound_claims.nomad_job_id` is the actual `job "..."` name in the
+jobspec, which may differ from the policy name (e.g. policy
+`service-forgejo` binds to job `forgejo`). Update it when each bot's or
+runner's jobspec lands.
+
+### Adding a new service
+
+1. Write `vault/policies/<name>.hcl` using the naming-table family that
+   fits (`service-`, `bot-`, `runner-`, or standalone).
+2. Add a matching entry to `vault/roles.yaml` with all four fields
+   (`name`, `policy`, `namespace`, `job_id`).
+3. Apply both — either in one shot via `lib/init/nomad/vault-nomad-auth.sh`
+   (policies → roles → nomad SIGHUP), or granularly via
+   `tools/vault-apply-policies.sh` + `tools/vault-apply-roles.sh`.
+4. Reference the role in the consuming jobspec's `vault { role = "<name>" }`.
+
+### Token shape
+
+All roles share the same token shape, hardcoded in
+`tools/vault-apply-roles.sh`:
+
+| Field | Value |
+|---|---|
+| `bound_audiences` | `["vault.io"]` — matches `default_identity.aud` in `nomad/server.hcl` |
+| `token_type` | `service` — auto-revoked when the task exits |
+| `token_ttl` | `1h` |
+| `token_max_ttl` | `24h` |
+
+Bumping any of these is a knowing, repo-wide change. Per-role overrides
+would let one service's tokens outlive the others — add a field to
+`vault/roles.yaml` and the applier at the same time if that ever
+becomes necessary.
+
 ## What this directory does NOT own
 
 - **Attaching policies to Nomad jobs.** That's S2.4 (#882) via the
-  jobspec `template { vault { policies = […] } }` stanza.
-- **Enabling JWT auth + Nomad workload identity roles.** That's S2.3
-  (#881).
+  jobspec `template { vault { policies = […] } }` stanza — the role
+  name in `vault { role = "..." }` is what binds the policy.
 - **Writing the secret values themselves.** That's S2.2 (#880) via
   `tools/vault-import.sh`.
 - **CI policy fmt + validate + roles.yaml check.** That's S2.6 (#884).

+# vault/roles.yaml — Vault JWT-auth role bindings for Nomad workload identity
+#
+# Part of the Nomad+Vault migration (S2.3, issue #881). One entry per
+# vault/policies/*.hcl policy. Each entry pairs:
+#
+#   - the Vault role name (what a Nomad job references via
+#     `vault { role = "..." }` in its jobspec), with
+#   - the ACL policy attached to tokens it mints, and
+#   - the bound claims that gate which Nomad workloads may authenticate
+#     through that role (prevents a jobspec named "woodpecker" from
+#     asking for role "service-forgejo").
+#
+# The source of truth for *what* secrets each role's token can read is
+# vault/policies/<policy>.hcl. This file only wires role→policy→claims.
+# Keeping the two side-by-side in the repo means an S2.1↔S2.3 drift
+# (new policy without a role, or vice versa) shows up in one directory
+# review, not as a runtime "permission denied" at job placement.
+#
+# All roles share the same constants (hardcoded in tools/vault-apply-roles.sh):
+#   - bound_audiences = ["vault.io"]      — Nomad's default workload-identity aud
+#   - token_type      = "service"         — revoked when task exits
+#   - token_ttl       = "1h"              — token lifetime
+#   - token_max_ttl   = "24h"             — hard cap across renewals
+#
+# Format (strict — parsed line-by-line by tools/vault-apply-roles.sh with
+# awk; keep the "- name:" prefix + two-space nested indent exactly as
+# shown below):
+#
+#   roles:

+#
+# All four fields are required. Comments (#) and blank lines are ignored.
+#
+# Adding a new role:
+#   1. Land the companion vault/policies/<name>.hcl in S2.1 style.
+#   2. Add a block here with all four fields.
