Change

isOmoProcess took a foreground process for omo when any word of its argv was an omo path, so grep -q …/omo-ai/x, cat …/bin/omo or node watch.js …/omo-ai/plugin counted as omo. The sidebar then named the pane omo, the transcript lookup counted it as a second omo in the cwd, and startShellAgent could report a start.

Now only the program counts: argv[0], or, when argv[0] is node/nodejs/bun, the script it runs (the first word after it that is not a flag). The word must still be one path (no :), as #243 required.

Shapes kept, the first two exactly as herdr 0.9.0's pane.process_info reported them for omo 5.1.7 in a test pane:

• /home/u/.bun/bin/bun …/omo-ai/node_modules/@code-yeongyu/senpi/dist/bundle/cli.js --extension …/omo-ai/plugin
• /home/u/.bun/bin/bun …/omo-ai/plugin/runtime/ast-grep-mcp/cli.js mcp (omo's MCP child, same process group)
• node …/bin/omo, node --flag …/omo-ai/bin/omo.js, a native omo, and the SDK child …/omo-ai/…/claude

The change is confined to isOmoProcess and one regex above it in server/omo.ts; Windows paths (#234) are untouched.

Closes #248

Also checked: the omo question cards against real omo 5.1.7 (no defect found, no code change)

In the isolated herdr-web-ui-test session (herdr 0.9.0), a server from this branch, and a real omo asked for a two-question ask_user_question form:

• The card appeared with the form's title, options and step chips (Question 1 of 2, Red/Green/Blue, chips Color/Fruits), identical at 120, 60 and 40 columns.
• Single choice, multiple choice, a typed answer, reopening an answer from the review, and Submit each moved omo on; omo reported 2 answered; 0 unanswered with the answers sent. A stale answer got 409 prompt_changed.
• The footer was 2 lines under exactly one rule at all three widths.
• Backspace cleared an earlier multiple choice (Apple, Cherry -> Banana) and an earlier typed answer (Purple -> Teal).
• Options 10 and above cannot occur in omo 5.1.7: its tool refuses with options must contain 2 to 4 items when present.
• herdr reported the pane as pi before the first turn and claude with status idle (not blocked) while the form showed; the card still came from the session's pending call.

Validation

• bun run typecheck passes.
• bun run test:unit: 673 pass, 0 fail (two new tests in server/omo.test.ts, one per direction).
• bun test ./server/omo.contract.test.ts ./server/omo-prompt.contract.test.ts ./server/prompt.contract.test.ts: 10 pass.
