On Linux the CLI installs as orca-ide so it never shadows /usr/bin/orca
(GNOME's screen reader), but agent-facing surfaces (orca-cli skill,
dispatch preambles, CLI hints) all invoke bare `orca` — so on stock
Ubuntu an agent inside an Orca terminal launched the screen reader,
which started speaking (#7904).
Fix: prepend a userData-scoped shim dir (bare `orca` -> bundled
orca-ide launcher, or the stable AppImage) to the PATH of every
packaged-Linux managed PTY, mirroring the existing dev-mode cli/bin
prepend. The user's own shells — and their real screen reader command —
stay untouched. Also flip the orca-cli skill probe to prefer orca-ide
so agents outside Orca terminals never execute the screen reader.
