oab-instance-mcp 0.6.5

Highlights

First release with Linux hands-node artifacts. oab-instance-mcp now ships a Rust build for
Linux alongside the macOS installer, so a cheap Linux box (Raspberry Pi, Intel mini PC) can be a
lendable "hands" node for openab-pty and OpenAB Connect.

Artifacts

Platform	Asset
macOS (universal, signed + notarized)	oab-instance-mcp-0.6.5-universal.pkg, .app.zip
Linux arm64 (Raspberry Pi, aarch64)	oab-instance-mcp-0.6.5-linux-arm64.tar.gz
Linux amd64 (x86-64)	oab-instance-mcp-0.6.5-linux-amd64.tar.gz

Each has a .sha256; macOS assets are also in SHA256SUMS. Linux install:
docs/linux-setup.md.

What's new (Linux, PoC)

• Rust hands node (poc/reverse-attach-linux/): reverse attach (POST /attach, mint or
  pre-minted secret, WS dial with the §9.2 disposition table), MCP over /mcp behind the Swift
  daemon's AuthPolicy (bearer AND Tailscale login), and tools sys_info, screenshot (grim →
  MCP image), bash, mouse (wlrctl), key (wtype). Re-serves an upstream @playwright/mcp
  as browser_*, filtered by profile. (#29)
• Setup guide + installer: docs/linux-setup.md, scripts/install-linux.sh, and CI that
  builds/smoke-tests on native amd64/arm64 and ships the tarballs. (#30)
• ADR: Linux input via wlrctl (wlroots), not ydotool. (#26)

Verified on a Raspberry Pi (labwc) end to end: lent to an openab-pty session, driven from
OpenAB Connect's Screens pane, browser navigate/snapshot.

macOS behaviour is unchanged from 0.6.4.
