Release candidate

Prepare session-peer v0.8.0 after #76, #77, #78, #80, and #82 were merged in dependency order with passing CI. This release combines unified Claude/Codex discovery, optional MCP tools and a Codex plugin, bounded opt-in Codex wake, default/Orca/custom home listing, and explicit message/output-format options.

Bump the package version, add release notes, and refresh README verification and the release runbook. Pin two update-notice test fixtures to their intended installed version so future release bumps do not invalidate their newer-version comparisons.

Validation

• MCP environment: 301 tests passed.
• Standalone explicit/default discovery: 301 tests each, two optional SDK tests skipped.
• Compile and diff checks passed; wheel/sdist built and independently installed into fresh environments.
• Both artifacts report 0.8.0 and support isolated-home JSON listing; optional MCP wheel extra and entrypoint checked.
• Distribution contents include the adapter/plugin documentation as appropriate and exclude legacy cc_peer.py.
• No live messages or wake activations during release preparation.

Wake remains limited to Codex CLI 0.154.0 on macOS/Linux, with earlier live model validation on macOS only. Queue/wake results do not confirm receipt of a particular item.
