Update JavaScript dependencies

[samuel-williams-shopify]

Update the JavaScript dependencies and reduce the checked-in Mermaid distribution to the runtime files Utopia Project actually uses.

• Update Mermaid from 11.12.0 (locked; ^11.4.1 declared) to 11.16.1
• Update transitive dependencies, including DOMPurify to 3.4.13
• Keep @socketry/syntax at the current 0.5.0
• Configure utopia:components:update to vendor only mermaid.esm.min.mjs and its minified ESM chunks
• Temporarily pin Utopia to Support selecting component package files utopia#74 until the component selection support is released
• Remove unused core, unminified ESM, UMD, and source-map distributions
• Reduce the vendored Mermaid footprint from about 66 MB to 3.8 MB

Validation:

• bake utopia:components:update reproduces the manually curated component tree byte-for-byte: 197 files with no added, removed, or changed hashes
• All 104 vendored Mermaid runtime modules are reachable from the imported entry point
• All static and dynamic module imports resolve within the vendored distribution
• No unused runtime modules or stale source-map references remain
• npm outdated reports no remaining updates
• npm audit --omit=dev reports zero vulnerabilities
• Mermaid flowchart and sequence parsing smoke tests pass
• Ruby test suite: 17 examples, 17 passed
