Rename Tape to Options and Replace the Web Rail

Summary

The Tape surface is now presented to users as Options, with /options as the canonical web route and /tape preserved as a compatibility redirect. The shared web shell no longer reserves a persistent left rail; every route now gets full-width content under a sticky top header, with navigation, branding, and shell metrics moved into a top-left overlay drawer.

Changes Made

• Added canonical web route /options via apps/web/app/options/page.tsx and changed apps/web/app/tape/page.tsx to redirect to it.
• Updated route helpers in apps/web/app/terminal.tsx so /options is canonical while /tape remains accepted during transition.
• Renamed top-level navigation copy from Tape to Options.
• Replaced the persistent web rail with a sticky header plus overlay drawer in apps/web/app/terminal.tsx and apps/web/app/globals.css.
• Changed the Options page layout to a full-width two-section stack: OptionsPane first, FlowPane below with title Packets, and removed EquitiesPane from this route.
• Updated route, redirect, and desktop trust tests plus desktop README guidance to prefer /options while documenting /tape compatibility.

Context

This change consolidates two related UX issues: the product naming mismatch around the Tape surface, and the layout cost of the always-visible left rail. The product/design context for Islandflow emphasizes investigation workflows, stable rhythm under live updates, and full-width evidence surfaces over decorative chrome.

Important Implementation Details

• normalizeTerminalPathname() now treats /tape as an alias of /options, which keeps route-feature decisions, live subscriptions, and nav highlighting aligned from one helper.
• The new Options route intentionally drops the Equities subscription and pane. The canonical route now subscribes only to options, nbbo, and flow.
• The drawer closes on route change, backdrop click, and Escape via client-side state in TerminalAppShell.
• Desktop trust remains origin-based, so no Electron security model change was required. The desktop updates only clarify preferred route examples and add explicit /options coverage.

Expected Impact for End-Users

Users now land on a more clearly named Options route, keep old /tape links working, and get more horizontal space across the web app because navigation no longer consumes a permanent left column. The Options route is simpler and more focused: options flow first, packets below, without the Equities panel competing for width.

Validation

• Passed: bun test apps/web/app/routes.test.ts apps/web/app/terminal.test.ts apps/desktop/src/security.test.ts (85 passing tests).
• Passed: bun --cwd=apps/web run build including production build, TypeScript, and app-route generation for /options and /tape.
• Skipped by request: browser visual probes for the drawer/header refactor.

Issues, Limitations, and Mitigations

• The current web test suite is still mostly route/helper-level, so the new drawer interactions are not covered by DOM/browser tests yet. Mitigation: filed follow-up issue islandflow-3by.
• Internal code still uses some Tape-named helpers and hooks. This was left intentionally to keep the rename low-risk while user-facing copy and routing moved to Options.
• The Options route no longer shows Equities. That is intentional for layout clarity, but it does change the previous multi-pane surface composition.

Follow-up Work

• islandflow-3by: add interaction coverage for drawer open/close, Escape dismissal, backdrop dismissal, and route-change dismissal.
• If we later want a broader naming cleanup, isolate internal Tape* renames into a separate low-risk refactor rather than coupling them to route behavior again.
