- 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, err := CdpConnect(9222)
|
|
if err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
defer CdpClose(conn, 0)
|
|
```

## Notas
|
|
|
|
El WebSocket se implementa desde cero usando `net.Dial` + handshake HTTP Upgrade + framing RFC 6455. Esto evita dependencias externas. Solo soporta frames no fragmentados (suficiente para CDP que envia mensajes completos).
|
|
|
|
El struct `CDPConn` y toda la infraestructura WebSocket/CDP se define en `cdp_conn.go` dentro del mismo paquete `infra`.
|
|
|
|
La goroutine `readLoop` enruta respuestas a channels por ID de mensaje. Los eventos CDP sin ID son ignorados (las funciones que necesitan eventos usan polling).
