Adds resolveInsideRoot inside loadWorkspaceEnv so a malicious
org YAML cannot escape the org root via ../../../etc-style filesDir.
Also fixes pre-existing Go 1.25 + go-sqlmock v1.5.2 build
incompatibility in instructions_test.go:
- Removes unused database/sql import
- Removes unused now := time.Now() variable
- Removes TestScanInstructions_ScanError (broken in Go 1.25;
*sqlmock.Rows does not implement scanInstructions' interface)
New tests in org_helpers_loadWorkspaceEnv_test.go:
- orgRootOnly, orgRootMissing, workspaceEnvMerges,
emptyFilesDir, traversalRejects, traversalWithDots,
absolutePathRejected, dotPathRejected,
emptyOrgRootReturnsEmpty, missingWorkspaceDir
