Pull request overview

Adds Unix socket discovery to the database instance auto-discovery flow and standardizes how connection targets are displayed (including Unix socket targets), enabling users to discover/connect to local PostgreSQL instances that expose only a socket.

Changes:

Added a Unix socket scanner that searches common socket directories and integrates results into overall discovery.
Introduced DisplayTarget() / UsesUnixSocket() helpers on connection/discovery models and updated UI/error rendering to use them.
Centralized “discovered instance → connection config” logic into a dedicated builder and updated connection flows to use it.

…words BuildConnectionConfig returned GetEnvironmentConfig() verbatim for the environment source, carrying Name="Environment" and the PGPASSWORD/ .pgpass password into the connection pipeline. - Clear Name on the env path so the connection ID and history entry fall back to ConnectionLabel() (e.g. user@host:port/db), matching the other discovered sources instead of producing duplicate "Environment" history entries and a fixed connection ID. - Clear Password on both the env and .pgpass paths. pgx still resolves the credential via libpq defaults (PGPASSWORD env, ~/.pgpass), so connections authenticate unchanged, but the password no longer gets persisted to the OS keyring on success.

Strip leading/trailing spaces from PGHOST/PGPORT/PGDATABASE/PGUSER/ PGSSLMODE so connection strings stay valid. Leave PGPASSWORD untrimmed.

Bound listenPostgresSocket Accept with a deadline and a select timeout so a missed dial cannot hang tests. Stop filling Password in buildPgPassConfig; libpq reads ~/.pgpass and we intentionally keep secrets out of the keyring.
