Tecton + support for String operations

[marron-at-work]

FString -- support and tests
String regex -- support and tests
Cleanup for tecton

[Copilot]

🟡 Changes recommended

Tecton currently performs an invalid hard-coded lookup and fails for most primitive types.

Once you've addressed the issues Copilot identified, you can request another Copilot review.

Pull request overview

Adds Unicode String interpolation and regex support while extending Tecton component generation.

Changes:

• Implements FString parsing, checking, C++ emission, and execution.
• Adds String regex/type-alias support using Boost ICU.
• Extends Tecton formats and renames regex BAPI declarations.
