chore(release): prepare v0.16.0

[chaliy]

What changed

Prepares Bashkit v0.16.0 across Rust, CLI, Python, native Node, browser WASM, and C ABI release artifacts. The release adds host-backed browser filesystems, byte-native streams, typed and revocable execution boundaries, jq-backed yq, bzip2 interoperability, and truthful time reporting.

The changelog includes migration guidance for StreamData, execution-scoped host capabilities, and replacing the removed yaml helper with yq. Self-hosted TypeScript API references are refreshed for execution profiles and raw-byte result fields.

Why

There are 34 verified commits since v0.15.0, including new public APIs and intentional breaking changes that require a minor release. Local history and the GitHub compare API both report 34 commits; all public registries currently report v0.15.0.

Before / After

Before:

cargo search bashkit                 -> 0.15.0
pip index versions bashkit           -> 0.15.0
npm @everruns/bashkit latest         -> 0.15.0
npm @everruns/bashkit-wasm latest    -> 0.15.0

Prepared and smoke-tested:

bashkit 0.16.0
yq smoke                 -> ["apple","pear"]
bzip2 | bzcat smoke      -> binary-smoke
time smoke                -> status=0 commands=1
Python ABI3 wheel         -> 0.16.0 python-wheel-smoke
C ABI consumer            -> Hello from Bashkit! User: sandbox Time: ...
Node release tests        -> 554 passed
Browser WASM tests        -> 63 passed

Publish-readiness:

• just release-check passed: fmt, clippy, full Rust/unit/integration/doc/security suite, script tests, capability parity, OKF, doc links, cargo-vet, nightly/fuzz health.
• cargo publish --dry-run -p bashkit packaged and verified v0.16.0.
• Disposable registry-backed bashkit-cli package dry-run succeeded.
• Native Node optimized build, TypeScript compile, and tests passed.
• Browser WASM optimized build and headless integration suite passed.
• Python cp39-abi3 release wheel built, installed into a clean environment, and executed.
• C shared library built, linked with -std=c11 -Wall -Wextra -Werror, and executed.

Risk

• Medium
• This is a multi-registry minor release with intentional public API changes documented in the changelog.
• Publishing remains CI-managed; post-merge monitoring will verify GitHub Release, crates.io, PyPI, both npm packages, Homebrew, and all C ABI archives before declaring the release shipped.

Checklist

• Tests added or updated
• Backward compatibility considered
