chore: release v0.7.16

[avifenesh]

Release the KWin source-build fix from #252 as v0.7.16. Update Cargo, npm, MCP, Pi and plugin versions together and add the changelog entry.

Validation: full tests and Rust 1.93.1 all-target compilation passed for #252. Formatting, plugin version checks, npm package checks and diff checks passed for the release metadata.

Note

Low Risk
Metadata-only release bump with no runtime code changes in this PR; the shipped fix is a narrow KWin build-compat change from #252.

Overview
Release v0.7.16 packages the KWin source-build fix from #252 (already merged) and keeps every consumer-facing version string in sync.

The changelog records replacing the KWin backend’s atomic update API with stable Rust primitives so source builds succeed on Rust 1.93.1. This diff does not include that Rust change—only 0.7.15 → 0.7.16 bumps across Cargo.toml / Cargo.lock, npm (package.json), MCP server.rs tool handler version, Pi GENERATED_SERVER_VERSION, Claude/Codex plugin manifests, marketplace metadata, and the plugin launcher’s pinned download version, plus changelog links for 0.7.16.

I found nothing left at 0.7.15 in Cargo.toml, Cargo.lock, package.json, the MCP server version string, the Pi tool catalog, the plugin manifests and the plugin launcher script. One small release-metadata gap: the CHANGELOG link references at the bottom of the file weren't updated for 0.7.16.
