fix(daemon): socket path shortening for long workspace paths
Fixes GH#1001 where long workspace paths (e.g., pytest temp directories) caused
socket path mismatches. The daemon now uses rpc.ShortSocketPath() consistently
with the client.
Changes:
- daemon.go: Use rpc.ShortSocketPath() + EnsureSocketDir() for daemon socket
- daemon_config.go: Update getSocketPathForPID() to use rpc.ShortSocketPath()
- Added tests for long path handling and client-daemon socket path agreement

The daemon socket tests relied on an external assertion library, which
increased the module's dependency footprint and deviated from Go's
idiomatic testing patterns.
This commit introduces a leaner testing approach using the standard
library:
- Replace testify/assert calls with standard if checks and t.Errorf
- Remove testify and associated indirects from go.mod
These changes preserve existing test behavior while simplifying the
build process and reducing external maintenance overhead.
Add BD_SOCKET environment variable support to override daemon socket path,
enabling parallel test isolation via t.TempDir() + t.Setenv().
Changes:
- getSocketPath() checks BD_SOCKET first, falls back to dbPath-derived path
- getSocketPathForPID() checks BD_SOCKET first (for consistency)
- Add daemon_socket_test.go with isolation pattern examples
This is a minimal tracer bullet to validate the approach before
expanding to full test isolation infrastructure.
Backward compatible: default behavior unchanged without env var set.
