* improvement(seo): optimize sitemaps and robots.txt across sim and docs

- Add missing pages to sim sitemap: blog author pages, academy catalog and course pages
- Fix 6x duplicate URL bug in docs sitemap by deduplicating with source.getLanguages()
- Convert docs sitemap from route handler to Next.js metadata convention with native hreflang
- Add x-default hreflang alternate for docs multi-language pages
- Remove changeFrequency and priority fields (Google ignores both)
- Fix inaccurate lastModified timestamps — derive from real content dates, omit when unknown
- Consolidate 20+ redundant per-bot robots rules into single wildcard entry
- Add /form/ and /credential-account/ to sim robots disallow list
- Reference image sitemap in sim robots.txt
- Remove deprecated host directive from sim robots
- Move disallow rules before allow in docs robots for crawler compatibility
- Extract hardcoded docs baseUrl to env variable with production fallback

* fix(seo): remove homepage new Date(), guard latestModelDate empty array

* improvement(seo): consolidate DOCS_BASE_URL, optimize core web vitals

Extract hardcoded https://docs.sim.ai into shared DOCS_BASE_URL constant
in lib/urls.ts and replace all 20+ instances across layouts, metadata,
structured data, LLM manifest, sitemap, and robots files. Remove
OneDollarStats analytics script and tighten CSP for improved core web vitals.

* fix: removed onedollarstats from bun lock

* fix(seo): guard per-provider Math.max, consolidate docs robots to single wildcard
