docs+config: propagate proposals 0001/0002 [accepted]+ADR status across stale references

[hyperpolymath]

Summary

Companion to #115 (acceptance flip) and #116 (ADR promotion). Sweeps the
remaining files that still carried [draft] / [review] proposal status
or referenced now-closed cross-repo gating issues.

Files changed

File	What changed
`README.adoc`	Proposal status flipped to `[accepted]` + ADR links; added 0003/0004 to forward-looking section; rewrote the verifier-pass status sentence (was "gated on proposal 0002's acceptance"; now reflects PR #109 having shipped).
`CHANGELOG.md`	New Unreleased section "Multi-producer carrier ABI: proposals 0001 + 0002 accepted, promoted to ADRs (2026-05-30)" covering PRs #110-#116 + the seven closed issues + producer-side gates that remain.
`crates/typed-wasm-verify/Cargo.toml`	Feature-flag comments updated to reflect post-acceptance state. `unstable-l2` / `unstable-l15` feature gates retained while Phase 3 stabilisation is open.
`docs/PRODUCTION-PATH.adoc`	Proposals 0001/0002 flipped to `[accepted]` with PR pointers; added 0003/0004 to active-design-work list.
`spec/type-safety-levels-for-wasm.adoc`	Wire-section status column updated for `typedwasm.regions` / `typedwasm.capabilities` / `typedwasm.access-sites`; tail references enumerate all four proposals with current status.
`.machine_readable/6a2/STATE.a2ml`	Capabilities-by-level entries flipped 30→100; rewrote critical-next-actions; rewrote `[carrier-abi]` section with accepted-date / acceptance-pr / adr-pr for both proposals + added `[draft]` entries for 0003/0004.

What was deliberately left alone

`spec/{ARG,CRG,FRG,TRG}-PROFILE.adoc` — these are point-in-time audit
snapshots, not config. They mention the proposals as the live RFC
corpus, but rewriting audit history adds more noise than signal.

Test plan

• CI green (docs + config only; no source changes)
• Cross-links resolve in rendered AsciiDoc
