docs: label Go analysis as experimental

Align consumer-facing language claims with verified analyzer
capabilities. Go has a real bounded Tree-sitter parser participating in
symbol/import/call extraction, route analysis, and architecture graph
construction, but lacks first-class entrypoint recognition (func main /
package main / main.go), complete router attribution (Gin/Echo conflation,
no Chi/Fiber), dedicated fixtures/goldens, and Python-engine parity, so it
is explicitly labelled experimental rather than supported.

- README pitch: experimental Go analysis covering the structural map.
- package.json description: experimental Go support.
- Landing hero subtitle: experimental Go analysis.
- pyproject.toml (Python engine) intentionally unchanged: that engine
  does not analyze Go.

+RepoDNA turns unfamiliar Python, JavaScript, and TypeScript repositories into interactive structural maps, with experimental Go analysis for files, symbols, imports, routes, databases, external systems, architecture layers, execution traces, impact slices, and onboarding.
 
 It is deterministic, local-first, and does not use an LLM. The analyzer reads source code as text and **never executes repository code**.
