Jinwoo-H eb7e27ba0b skills: rewrite the seven non-orchestration guides to one outcome-first standard
Every guide leads with Result / Done / Safe failure, states conditions instead of case lists, keeps one done bar and one autonomy envelope, and loads references at the point of use via `skills get <topic> --full`. orca-cli drops from 424 to 260 always-loaded lines with three references; orca-per-workspace-env from 794 to 397 with five.

Defects fixed in shipped guides: `emulator camera` (no such command), iOS `permissions` (backend refuses it), Android pane described as in development, `relayGracePeriodSeconds: 0` documented as immediate teardown (it is unbounded), doctor `ok: true` hiding `warn`, an SSH exemplar setting both `jumpHost` and `proxyCommand`, a provisioned-root fetch from `origin`, and the Linear unconfirmed-write rule keyed on four verbs when ten emit it.

The resolver ladder, placeholder rule, and older-binary fallback shared by every installable SKILL.md now come from one skill-stubs/_shared/cli-resolution.md fragment composed by the generator, which also bundles per-guide references into --full. New guards: every ORCA invocation and flag resolves against COMMAND_SPECS, descriptions carry no angle-bracket tokens, reference routing is checked both ways, and an always-loaded size ratchet (300 lines) that guides may leave but never join.
