Current branch update after 1cc4c23:

Summary:

• Adds markmap-embed for SVG embeds, auto-resize, node events, themes, iframe host messaging, HTTP persistence, and origin hardening.
• Adds React/Vue/Svelte adapters plus hosted iframe helper components.
• Adds examples/mindmaps-playground and services/mindmaps-api demo flow with recent maps, search, clone/delete, titles, and session auth.
• Fixes root recursive pnpm lifecycle scripts for pnpm 11 compatibility.

Verified locally:

• pnpm build
• pnpm test:embed:browser
• git diff --check

Note: gh pr checks reports no checks for this branch.

Split-out started for easier review:

• Add embeddable Markmap package and adapters #354 contains the core markmap-embed package, React/Vue/Svelte adapters, parser support, and pnpm 11 script fix.
• Keeping this larger PR open as the full feature branch/reference while smaller PRs are reviewed.

Second split branch prepared:

• adepalma:codex/markmap-host-sdk contains the host iframe SDK, custom element, React/Vue host-frame adapters, docs, and tests.
• It is stacked on Add embeddable Markmap package and adapters #354, so I am keeping it as a fork-side stacked branch until Add embeddable Markmap package and adapters #354 lands to avoid opening an upstream PR with duplicate core diff.

Third split branch prepared:

• adepalma:codex/markmap-playground contains the Vite playground, HTTP persistence demo UI, services/mindmaps-api, and host-example Playwright coverage.
• It is stacked on codex/markmap-host-sdk, which is stacked on Add embeddable Markmap package and adapters #354. Keeping it fork-side until earlier layers land to avoid duplicate upstream diff.
