Selectors:
  --repo <selector>         Registered repo selector such as id:<id>, name:<name>, or path:<path>
  --worktree <selector>     Worktree selector such as id:<id>, branch:<branch>, issue:<number>, path:<path>, or active/current
  --terminal <handle>       Runtime-issued terminal handle returned by \`orca terminal list --json\`

Terminal Send Options:
  --text <text>             Text to send to the terminal
  --enter                   Append Enter after sending text
  --interrupt               Send as an interrupt-style input when supported

Wait Options:
  --for exit                Wait until the target terminal exits
  --timeout-ms <ms>         Maximum wait time before timing out

Output Options:
  --json                    Emit machine-readable JSON instead of human text
  --help                    Show this help message

Behavior:
  Most commands require a running Orca runtime. If Orca is not open yet, run \`orca open\` first.
  Use selectors for discovery and handles for repeated live terminal operations.

Browser Workflow:
  1. Create or navigate:  orca tab create --url https://example.com
                          orca goto --url https://example.com
  2. Inspect the page:    orca snapshot
     (Returns an accessibility tree with element refs like e1, e2, e3)
  3. Interact:            orca click --element e2
                          orca fill --element e5 --value "search query"
                          orca keypress --key Enter
  4. Re-inspect:          orca snapshot
     (Element refs change after navigation — always re-snapshot before interacting)

Browser Options:
  --element <ref>           Element ref from snapshot (e.g. e3, not @e3)
  --url <url>               URL to navigate to
  --value <text>            Value to fill or select
  --input <text>            Text to type at current focus (no element needed)
  --expression <js>         JavaScript expression to evaluate
  --key <key>               Key to press (Enter, Tab, Escape, Control+a, etc.)
  --direction <dir>         Scroll direction: up, down, left, right
  --amount <pixels>         Scroll distance in pixels (default: viewport height)
  --index <n>               Tab index (from \`tab list\`)
  --format <png|jpeg>       Screenshot image format
  --from <ref>              Drag source element ref
  --to <ref>                Drag target element ref
  --files <path,...>        Comma-separated file paths for upload
  --timeout <ms>            Wait timeout in milliseconds
  --worktree <selector>     Scope commands to a specific worktree's browser tabs

Examples:
  $ orca open
  $ orca status --json
  $ orca repo list
  $ orca worktree create --repo name:orca --name cli-test-1 --issue 273
  $ orca worktree show --worktree branch:Jinwoo-H/cli
  $ orca worktree current
  $ orca worktree set --worktree active --comment "waiting on review"
  $ orca worktree ps --limit 10
  $ orca terminal list --worktree path:/Users/me/orca/workspaces/orca/cli-test-1 --json
  $ orca terminal send --terminal term_123 --text "hi" --enter
  $ orca terminal wait --terminal term_123 --for exit --timeout-ms 60000 --json
  $ orca tab create --url https://example.com
  $ orca snapshot
  $ orca click --element e3
  $ orca fill --element e5 --value "hello"
  $ orca goto --url https://example.com/login
  $ orca keypress --key Enter
  $ orca eval --expression "document.title"
  $ orca tab list --json`)
