chore: remove agent-os (salvage architecture docs + ADRs first)

[goosewobbler]

Why

Agent OS's spec-first scaffolding was built to micromanage agentic workflows with spec-first guardrails — a problem this project no longer has (and one its own author now considers obsolete). This removes it, keeping the parts that carry lasting value.

What this does

Two commits, salvage-then-remove:

1. Salvage the keepers (docs: salvage …)

• Architecture references → docs/architecture/ — the 14 project-specific standards from agent-os/standards/global/ (mock architecture, service split, driver lifecycle, binary discovery…) that describe this codebase, with a README index.
• Forward-looking specs → docs/design/ — mobile-service-convergence.md (linked from ROADMAP; describes unbuilt work) and the on-hold electrobun-multi-instance-upstream-draft.md.
• 3 ADRs distilled from the historical specs before they were deleted:
  • 0002 — Tauri defaults to an in-app embedded WebDriver server (macOS without a subscription; CrabNebula/external weighed and rejected).
  • 0003 — copy the reference service; extract shared code only on the Rule of Three (the built-then-deleted native-utils base-class story).
  • 0004 — Electrobun is driven over CDP; the default WebKit renderer is unsupported.
• Repointed every reference into moved/deleted content: AGENTS.md, ROADMAP.md, the electrobun mock.ts comment, and the kept add-native-service skill now point at docs/. The 9 electrobun "Framework gaps" comments (which cited a since-deleted plan) now cite the Electrobun: track upstream CEF fixes (Linux/Windows, multiremote, multi-window, deeplink) #320 CEF umbrella issue. Dropped the agent-os ignore-glob / doc examples in eslint.config.js and detect-changes.

2. Remove agent-os (chore: remove agent-os …)

• All of agent-os/ (config, product/mission.md, the generic backend/frontend/testing standards boilerplate, and the historical specs — the code is the spec for what shipped; ADRs capture the decisions).
• .claude/commands/agent-os/ (9 workflow commands) and .claude/agents/agent-os/ (8 spec/implementation subagents).
• 15 standards-wrapper skills: the backend-*/frontend-*/testing-* boilerplate and the 6 global-* skills (which linked to standards files that never existed).

Kept: the add-native-service skill (project-specific, independent of the spec-first workflow).

Notes for review

• git grep -i agent-os is now zero across the tree.
• Net +213 / −20,214 — almost entirely the deleted specs, boilerplate standards, and workflow command/agent definitions.
• The salvaged standards moved verbatim (git detects them as renames); the ADRs are the only new prose.
