- Migration 007: repo_url on apps table + analysis table with FTS5 - Analysis struct, parser, CRUD, validation, hash computation - Selective purge: remote-only apps/analysis preserved across fn index - CLI: fn app list/clone/pull, fn analysis list/clone/pull - search/show/list now include analysis results - Apps removed from git tracking (content lives in Gitea repos) - .gitkeep for apps/ and analysis/ dirs - Bash functions: jupyter analysis pipeline, shell utilities - Browser domain: CDP functions moved from infra to browser Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

## Ejemplo
|
|
|
|
```go
|
|
conn, _ := CdpConnect(9222)
|
|
result, err := CdpEvaluate(conn, "document.title")
|
|
// result = "My Page Title"
|
|
|
|
sum, err := CdpEvaluate(conn, "1 + 2")
|
|
// sum = "3"
|
|
```

## Notas
|
|
|
|
Los valores no-string se convierten con `fmt.Sprintf("%v", value)`. Numeros aparecen sin decimales si son enteros (ej: `"3"` no `"3.0"`). Para tipos complejos (objetos, arrays), el resultado es la representacion Go de la interfaz, no JSON — usar `JSON.stringify(...)` en la expresion JS para obtener JSON limpio.
