chore(rivet): mark shipped requirements as implemented

[avrabe]

Brings rivet requirement statuses in line with what has shipped on main: 24 draft + 2 planned (SR-33, SR-35) → implemented via rivet modify --set-status. Diff is status-line-only (26 lines).

Basis — implemented = code exists and works (full test suite green; real components fused + executed under wasmtime by the runtime tests). Not verified (per-requirement formal verification is a separate pass).

• SR-35 DWARF address remap → v0.16–v0.20 (DwarfHandling::Remap); in-tree witness oracle passes. Its stated verification is a cross-repo witness smoke that is not yet done, so implemented, not verified.
• SR-33 cross-component stream fusion → v0.9.0 (P3 async — cross-component stream adapter (#94 sub-A) #141).
• SR-31 multiply-instantiated detection → LS-M-5 (ls_m_5_*).
• SR-19 deterministic output → LS-A-15.
• SR-1..SR-25 parser / canonical-ABI / merger / adapter / wrapping subsystems → shipped across v0.1–v0.20.

Held at planned (honesty — not on main):

• SR-34 static stream validation — (i)/(iii) merged, (iv) is in the unmerged PR feat(p3): static resource-lifetime validation for async streams (#142 iv, v0.21.0) #210, (ii) bounded-capacity is N/A. Flip when feat(p3): static resource-lifetime validation for async streams (#142 iv, v0.21.0) #210 merges.
• SR-36 synthesised DWARF DIEs for adapters — DWARF Phase 3 (DWARF Phase 3: synthetic DIEs for adapter / inlined code (#130) #144), not started.

rivet validate error count unchanged (164 pre-existing schema-drift / broken-link errors; none introduced). Those pre-existing validation issues + tooling friction hit during this pass are filed upstream as pulseengine/rivet#353.

_{Approved loss-scenarios.yaml entries are expected to have a
regression test named ls_<letter>_<num>_* (e.g. LS-A-11 →
ls_a_11_*). The gate runs each prefix via cargo test --lib --no-fail-fast and aggregates pass/fail/missing.}
