Progress: SEF URLs foundation laid in haih-agent

One of the areas that may hinder SEO has been identified: the public URLs of fi1osof.ru are built around technical CUIDs (/tasks/<id>, /projects/<id>) and do not contain page semantics.

Since fi1osof.ru runs on haih-agent, the foundation itself was improved first. Commit https://github.com/haih-net/agent/commit/1f99a51dd407eb4e58f9e2f83f411a265db2f24c implements:

• slugify for human-readable URIs;
• URI generation from the concept name;
• 301 redirect from the old URI when it changes;
• general logic for redirect rules;
• decodeURI for correct reading of percent-encoded addresses.

The next stage is to pull the changes into fi1osof.ru and apply SEF URLs to indexed entities, primarily task/project URLs, while preserving old links via redirects/canonical.
