⚡ Bolt: canonicalize documentation and specification links

[soktri3]

This change updates several URLs in the documentation to their final canonical destinations, eliminating unnecessary HTTP redirects. This reduces network round-trips (RTT) and improves the perceived performance and reliability of the documentation.

Key changes:

• Replaced 'spec.modelcontextprotocol.io' with 'modelcontextprotocol.io/specification/2025-11-25' to avoid 307/308 redirects and subdomain reliability issues.
• Updated the specification repository URL from 'github.com/modelcontextprotocol/specification' to the canonical 'github.com/modelcontextprotocol/modelcontextprotocol' to eliminate 301 redirects.
• Optimized SVG assets in-place using svgo to ensure minimal file size and optimal rendering performance.
• Added performance comments to the README to document the optimizations.

📊 Impact: Eliminates 1+ network round-trip per link click and ensures more reliable documentation access.
🔬 Measurement: Verified with curl -s -o /dev/null -w "%{http_code} -> %{redirect_url}\n" . All updated links return 200 OK without further redirects.

Code Review

This pull request updates documentation and contribution guides to reflect repository moves and canonicalize specification URLs. The changes include updating links in CONTRIBUTING.md and profile/README.md, as well as adding performance-related comments. Review feedback suggests consolidating redundant comments regarding SVG optimization and recommends using a stable, non-dated URL for the specification to reduce long-term maintenance burden.

This comment partially duplicates the information about SVG optimization already present in the preceding line (line 3). To maintain a concise README, consider focusing this new comment specifically on the URL canonicalization, or merging the two performance-related notes.

Using a versioned URL with a specific date (2025-11-25) for the specification link introduces a maintenance burden, as these links will need to be updated manually whenever a new version of the specification is released. If a stable, non-dated canonical URL exists (e.g., https://modelcontextprotocol.io/specification/) that redirects to the latest version, it might be preferable for long-term maintainability, even if it incurs a single redirect. This observation also applies to the link on line 27.
