docs: comprehensive 2026-06-02 update reflecting PRs #99/#100/#101 (#106)

## Summary

Documentation refresh reflecting today's three landings (PRs #99 / #100
/ #101). No SPDX-header touches anywhere; license content only
**verified** where it appears.

### Files edited
- `CHANGELOG.md` — adds PR #99 (5-fix bundle) entry; sharpens existing
PR #101 entry to match its actual owner-orchestrated intentional flip
rationale; notes PR #100 as already-cured.
- `CHANGELOG.adoc` — mirrors the `.md` updates in the canonical AsciiDoc
Unreleased section with per-file receipts (`dogfood-gate.yml`,
`.hypatia-ignore`, `object_storage.ex:374`, `surrealdb.ex:153`,
`fuzz/rust-toolchain.toml`, `coveralls.json`, ramp doc).
- `README.adoc` — new **CI & Coverage** subsection cross-linking
[`elixir-orchestration/coveralls-coverage-targets.md`](elixir-orchestration/coveralls-coverage-targets.md).
License section verified `MPL-2.0` (no edits).
- `.machine_readable/6a2/STATE.a2ml` — populates stub with `license` /
`coverage-elixir` / `cicd-main-reds` components + a `session-history`
entry for 2026-06-02 citing PRs and closed issues.
- `contractiles/trust/Trustfile` — TRUST invariant: workspace
`Cargo.toml` + `mix.exs` `license` fields match `LICENSE` body.
- `contractiles/must/Mustfile` — MUST invariants: `coveralls.json`
`minimum_coverage` matches `coveralls-coverage-targets.md` current
stage; workspace license fields match `LICENSE` body.

### Cross-links
- PR #99 — cicd 5-of-7 main-red fixes (license deferred to #82).
- PR #101 — closes #82 (workspace MPL-2.0 normalize,
owner-orchestrated).
- PR #100 — closed as already-cured (function references resolved in
`rust_client.ex`).
- Coverage ramp doc:
`elixir-orchestration/coveralls-coverage-targets.md` (Phase 1 → 50 by
2026-07-15; Phase 2 → 60 by 2026-09-01).

## Test plan
- [ ] CI green (or matches main-branch baseline reds known
pre-existing).
- [ ] Reviewer eyeballs CHANGELOG.adoc + .md for accuracy of per-file
receipts.
- [ ] Confirm `.machine_readable/6a2/STATE.a2ml` parses (a2ml lint).

+=== Fixed — Main-branch reds + workspace license (2026-06-02)
+
+==== PR #99 — five root-cause main fixes
+- *`dogfood-gate.yml`*: SHA-pin `actions/checkout` (drop floating reference).
+- *`.hypatia-ignore`*: add `rescript.json` carve-out for the canonical ReScript build config.
+- *`elixir-orchestration/lib/.../adapters/object_storage.ex:374`*: rename unused `key` → `_key`.
+- *`elixir-orchestration/lib/.../adapters/surrealdb.ex:153`*: rename unused `max_depth` → `_max_depth`; TODO retained for the wired-up traversal-depth surface area.
+- *`fuzz/rust-toolchain.toml`*: pin `nightly-2026-05-15` (stop moving-toolchain drift).
+- *`elixir-orchestration/coveralls.json`*: `minimum_coverage` `60` → `40`; new `elixir-orchestration/coveralls-coverage-targets.md` documents the staged ramp `40 → 50 → 60` with target dates.
+- License normalisation deliberately deferred — handled separately in #101.
+
+==== PR #100 — closed as already-cured
+- Function references all resolve in `rust_client.ex`; no diff needed.
+
+==== PR #101 — `chore(license): normalize workspace to MPL-2.0`
+- Owner-orchestrated, intentional flip per the 5-way licence policy (verisimdb is sole-owner).
+- All workspace `Cargo.toml` + `mix.exs` license fields now match the `LICENSE` file body.
+- Closes #82.
