* fix(pi): resolve OMP tab identity from the outer wrapper, not the wrapped pi (#6364)
OMP runs as a `shell → omp → pi` process tree and Orca recognizes both `omp`
and `pi` as distinct agents. The foreground-process readers scored the deepest
`+` foreground descendant, so they returned the wrapped `pi` engine instead of
the `omp` the user actually launched — and because the sampled `+` frame moves
between omp and pi across command boundaries, the read oscillated and the tab
icon/label flickered OMP↔Pi. It surfaced on Remote Host / SSH (only in a
worktree, only while working) where a mirrored/restored pane has no client-side
launchAgent to anchor identity, so the (host-read) foreground was the only
pi/omp signal — and it was wrong.
Fix the detection at its source so foregroundAgent is trustworthy everywhere
(local tab icon, exit detection, and the remote mirror):
- Add `resolveOuterWrapperForegroundProcess` (src/shared/foreground-wrapper-agent.ts):
when the recognized foreground winner shares a `titleIdentityGroup` with a
shallower recognized ancestor, return the shallowest — the outer wrapper.
Stable regardless of which of omp/pi holds the foreground at the sample; bare
Pi and cross-group reads (Codex, etc.) are unchanged.
- Wire it into both readers: local `agent-foreground-process.ts` and the SSH
relay `pty-shell-utils.ts`. Also harden the relay's fallback short-circuit so a
pi-compatible process reported by node-pty rescans for the omp wrapper instead
of trusting `pi` raw (never downgrading below the fallback).
Also unify the host-side publish path onto the shared owner resolver: the mobile
session snapshot builders now resolve pane ownership via `resolvePaneAgentOwner`
({launchAgent, hookAgent}) instead of a bespoke `launchAgent ?? foregroundAgent`,
so the host stops being a divergent fourth identity path and the hook's
host-stamped identity survives when launchAgent is dropped on a mirrored pane.
Tests: unit coverage for the wrapper resolver, `shell→omp→pi` ps trees for both
readers (outer omp, oscillating-frame, bare pi, node-pty pi fallback), and a
host-snapshot regression that keeps an OMP hook labeled OMP when the wrapped pi
child owns the foreground.
* fix(pi): harden wrapper foreground ownership
* fix(pi): preserve OMP ownership in daemon foreground reads
* fix(pi): retain OMP owner when process scans fail
