- 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)
|
|
CdpNavigate(conn, "https://example.com")
|
|
|
|
err := CdpScreenshot(conn, "/tmp/page.png", CdpScreenshotOpts{
|
|
FullPage: true,
|
|
Format: "png",
|
|
})
|
|
```
|
|
|
|
## Notas
|
|
|
|
El struct `CdpScreenshotOpts` tiene campos: `FullPage bool`, `Quality int` (JPEG), `Format string` ("png" o "jpeg"). Chrome retorna la imagen como base64 que se decodifica y escribe al disco.
