chore: version packages

Release 1.9.8 (aicodeman) and 0.1.8 (xterm-zerolag-input).

Fixes macOS session start (`posix_spawnp failed.`, issues #6 and #204):
node-pty ships its macOS spawn-helper as mode 0644 and macOS launches every
PTY through it. `scripts/fix-node-pty.mjs` (npm run fix:node-pty) chmods every
helper, prebuilds/ included, then verifies by really opening a PTY; the blind
Node-22+ rebuild is gone. `spawnPtyWithHelperRepair()` self-heals an already
broken install on the first failed spawn.

Adds the phone home screen (session overview under 430px, per-device
`mobileOverviewEnabled`, default ON) and a guided Tailscale path in
install.sh, plus `install.sh tailscale` to retrofit it.
