release: v0.1.0 — the initial release

- CHANGELOG: the 0.1.0 entry finalized for publish — the alkcall
  0.8.1 / alktunnels 0.2.1 bumps and the fuzzing adoption folded in
  (the crate is unpublished, so no separate hardening cut — the
  alktunnels 0.2.1 precedent only applies post-publish); the fuzz/
  workspace bullet added (three targets, 129 seeds, corpus-replay
  gate, campaigns clean)
- README: the Version 0.1 note aligned (alkcall 0.8.1 — the
  duplicate-adopt fix is directly relevant to the consumer open/adopt
  paths; alktunnels 0.2.1; the fuzz posture noted)
- docs/architecture/overview.md: dep tree 0.8.1 / 0.2.1

Verification: cargo test (376 default / 638 all-features), fuzz/shared
corpus replay (3 pass), clippy --all-targets -D warnings (default,
all-features, wasm32-unknown-unknown), fmt --check, doc, wasm32 check,
and cargo publish --dry-run --allow-dirty all green (64 packaged
files — fuzz/, docs/research|reviews|plans/, tasks/, .opencode/,
AGENTS.md all excluded)
