chore(hypatia): clear false-positive + stale-ref findings at source (issue #34) (#131)

## What

You sent the Hypatia scan artifact, so I triaged the **43 findings (5
critical, 8 high, 30 medium)** and fixed the unambiguous ones at source.
**Most important first: the 4 "critical secret" findings are FALSE
POSITIVES** — placeholder env-var examples in docs (`sk-...`,
`sk-ant-...`, `your-key-here`) that match the OpenAI/Anthropic
key-prefix regex. **No real secret is leaked.**

## Fixed in this PR (confident, source-level)
| Finding | Sev | Fix |
|---|---|---|
| `secret_detected` ×3 — installation.md | crit | placeholders →
`<your-openai-key>` / `<your-anthropic-key>` |
| `structural_drift/SD007` ×3 — CLAUDE.md | med | `STATE.scm…` → current
`.a2ml` paths |
| `missing_timeout_minutes` — push-email-notify.yml | med | direct job →
added `timeout-minutes: 5` (it's not a reusable-caller, so fixed not
exempted) |
| `coq_axiom` ×15 — ResourceAlgebra.v | med | FALSE POSITIVE (Coq
`Module Type` interface fields, not kernel axioms) → exempted in
`.hypatia-ignore` with rationale |

## Honest scope — what's NOT here, and why
I **cannot run Hypatia in this environment** (no Elixir; network locked
to the 5 repos), so I can't verify that a given edit actually clears a
given finding. I only included changes I'm confident about by
inspection. The rest of the issue-#34 backlog needs the tool in the
loop:

- **High-volume code findings** — `expect_in_hot_path` (157 in
`src/parser.rs`, 5 in my-mir, …) and `unwrap_without_check` (26 in
my-fmt, 3 in my-llvm, 2 in my-lint, 1 in my-hir). Real, but fixing 190+
sites blind and hoping each clears (and doesn't just move
`unwrap`→`expect`, which is a *different* rule) is not reliable. Needs a
verifiable burndown.
- **`transmute` / `unsafe_block` (my-llvm)** — almost certainly
necessary FFI; want a `// SAFETY:` review, not a blind edit.
- **Meta findings** — `code_scanning_alerts/CSA00x` (≈13; they flag the
*age* of existing alerts, self-resolving) and `git_state/GS007` (counts
non-main remote branches — these very PR branches). Not code-fixable in
a PR; `.hypatia-ignore`'s path-fragment format can't cleanly scope them
either.
- **`structural_drift/SD022` ×5** — docs referencing renamed dirs
(`src/hir/`→`crates/my-hir`, …); fixable but I'd be guessing the
intended current paths.

**Recommendation for the remainder:** with Hypatia runnable locally, do
a verifiable burndown of the code findings; for the meta/age findings,
either resolve the underlying alerts or accept them in
`.hypatia-baseline.json` (its purpose). I didn't blanket-baseline
because the repo's discipline is fix-don't-suppress, and baselining
critical/security findings blind would be wrong.
