fix(ci): unbreak workflow YAML and add a complete actions.lock (#49)

Remediates **GitHub Workflow Dependency Locking** (public preview, no
changelog entry), which rejects runs at `startup_failure` — zero jobs,
no logs, nothing in REST or GraphQL. Full analysis:
`hyperpolymath/standards#657`.

**Proven on `hyperpolymath/anamnesis`: 6 of 6 workflows dead → 0
`startup_failure`, 13 running.**

### Five steps, in order — each blocks the next

**1. Unbreak the workflow YAML.** Any `permissions:` carrying a scalar
with an indented mapping under it:
```yaml
permissions: read-all
  actions: read        # <- mapping under a scalar. Unparseable.
```
This reaches past the one file: **`gh actions-lock` refuses to run when
*any* workflow in the repo fails to parse**, so the repo can never
acquire a lockfile and can never self-heal.

**2. Repin `standards` reusables** off commits with no `actions.lock`.
The rejection requires the **callee** to be covered *at the pinned SHA*
— unsatisfiable at a pre-lockfile commit.

**3. Generate** the lockfile with `gh actions-lock`.

**4. Hand-add the reusable-caller entries the tool omits**, as
`'<path>': []`.

⚠️ Measured across 218 repos: `P(startup_failure | has lockfile) =
91.7%` vs `15.8%` without — because every workflow a lockfile **omits**
is rejected. **A partial lock is worse than none.** Running `gh
actions-lock` and stopping there is how this outage spread.

**5. Restore `SPDX-License-Identifier` to line 1**, which the tool
displaces with its own banner and which the workflow-security linter
greps via `head -1`.

### Verified before this PR was opened
`0` unparseable workflows · lockfile covers **every** workflow, no
omissions · SPDX on line 1 in **every** file. The script refuses to push
if any of the three fails.
