Bump version to 1.6.2

Same shape as 1.6.1 -- EnsureExprTk.ps1 also has a Mandatory
TargetDir parameter that Bootstrap.ps1 was failing to supply.
Match the vcxproj invocation: $Repo\third_party\exprtk.

+- **CI Bootstrap.ps1 smoke job: missing `TargetDir` arg on `EnsureExprTk.ps1`.** Same shape as the 1.6.1 cert fix — `EnsureExprTk.ps1` declares `TargetDir` as a mandatory parameter; the vcxproj target supplies `$(ProjectDir)third_party\exprtk` but Bootstrap.ps1 was calling it bare. Now matches the vcxproj invocation.
