docs+test: ROADMAP truthfulness audit + drift-detection aspect (closes Phase 0 housekeeping) (#60)

## Summary

Phase 0 housekeeping — the ROADMAP truthfulness audit that
`docs/PRODUCTION-PATH.adoc` §Phase 0 requires before advancing to Phase
1. Three real drifts found and fixed, plus a new aspect-test section
that catches this drift class going forward.

## Drifts found and fixed

### 1. `spec/10-levels-for-wasm.adoc` →
`spec/type-safety-levels-for-wasm.adoc`

The file was renamed but 5 callers still pointed at the old path:
- `ROADMAP.adoc`
- `README.adoc`
- `EXPLAINME.adoc` (twice)
- `.claude/CLAUDE.md`

All updated.

### 2. `EXPLAINME.adoc` Idris2 ABI table out of date

EXPLAINME described a pre-restructure architecture (Types.idr /
Layout.idr / Access.idr / Effects.idr / Linearity.idr / Foreign.idr).
The actual structure is `src/abi/TypedWasm/ABI/{Region, TypedAccess,
Pointer, Levels, Effects, Lifetime, Linear, MultiModule, Layout, Proofs,
SessionProtocol, ResourceCapabilities, Choreography, Tropical,
Epistemic, Echo, ModuleIsolation}.idr`.

Rewrote claim 3's evidence sentence and the full file table to match
reality, with each entry naming the actual load-bearing types from each
file (`Region.idr` → Schema, sizeOf, alignOf; `TypedAccess.idr` →
HostType, RegionPredicate; `Levels.idr` → Level1_InstructionValidity
through Level10_Linear data types; etc.).

### 3. `src/abi/Foreign.idr` doesn't exist

EXPLAINME's file table claimed `Foreign.idr` provided "FFI declarations:
C header generation from Idris2 ABI". The file doesn't exist (the FFI
surface is `ffi/zig/src/main.zig`, hand-maintained per the comment in
that file's header). Removed the stale row.

## Drift-detection: claim-envelope §8

To prevent this class of drift recurring,
`tests/aspect/claim-envelope.mjs` gets a new section 8 — "Path
references in docs resolve to real files":

- Scans README.adoc, ROADMAP.adoc, EXPLAINME.adoc, .claude/CLAUDE.md
- Matches repo-relative path tokens with extensions:
adoc/md/mjs/res/idr/zig/rs/ebnf/toml/ipkg
- Allowlist: cross-repo paths (`typedqliser/`, `affinescript/`,
`ephapax/`, `standards/`, `hypatia/`, `typell/`, `vql-ut/`, `echidna/`),
templated paths (`{{...}}`), well-known non-repo paths (`github.com`,
`/home/runner/`)
- Skip filter: bare filenames without `/` (those are prose conventions
like "see PROOF-NEEDS.md")
- Prints every stale reference inline (not first-5-only) since rename
drift is what reviewers must see in full

Section 8 now finds 31 path references across the 4 docs, all resolving.
Before this PR's fixes: 7 stale (the EXPLAINME refs to old `src/abi/`
paths).

## Verification

All test surfaces green after the changes:

| Test | Result |
|---|---|
| claim-envelope.mjs | **53 passed, 0 failed, 0 skipped** (was 52; +1
from new section 8) |
| property_test.mjs | 29 passed, 0 failed, 0 skipped |
| security-envelope.mjs | 10 passed, 0 failed, 0 skipped |
| regression.mjs | 25 passed, 0 failed, 1 skipped (idris2 not on PATH) |
| smoke/e2e-smoke.mjs | 40 passed, 0 failed |
| Structural E2E | 53 passed, 0 failed, 1 skipped |

## Files changed

- `.claude/CLAUDE.md` — spec path fix
- `EXPLAINME.adoc` — spec path fix + claim 3 evidence rewrite + file
table restructure
- `README.adoc` — spec path fix in Quick Tour
- `ROADMAP.adoc` — spec path fix in Current State
- `tests/aspect/claim-envelope.mjs` — new section 8 (path-reference
drift detection)

## Closes Phase 0

This PR completes the ROADMAP truthfulness audit checklist item in #48.
After it lands, Phase 0's housekeeping subsection is fully closed.
Remaining Phase 0 items are Track A's multi-PR codegen pipeline work and
Track B's cross-repo AffineScript migration — both outside what one
session can ship.
