feat(AB#1273974): repeat feature

[Artem Pogorelov (art-pogorelov)]

Overview

Add --repeat N and --repeat-tag-filter <expression> CLI options to re-run matching scenarios N times (useful for performance measurements, for example).
This mirrors the existing --retry pattern but runs unconditionally.

Behavior

--repeat 10 → every scenario runs 10 times
--repeat 10 --repeat-tag-filter "@Performance" → only scenarios tagged performance run 10 times; others run once
Default (--repeat 1 or omitted) → no behavior change
Each repeat is a full independent execution (hooks fire each time)
Exit code: fail if any repeat fails

Testing

Verify with:
runner.exe features --repeat 3 --repeat-tag-filter "@SomeTag"
Confirm the tagged scenario runs 3 times and untagged scenarios run once.

Pull request overview

Adds a “repeat” execution mechanism intended to mirror existing retry behavior, allowing selected scenarios to be executed multiple times for performance measurement.

Changes:

• Introduces repeat / repeatTagExpression into runtime run options and threads them through application/run options wiring.
• Updates the runtime Worker to run each matching test case multiple times and aggregate pass/fail across repeats.
• Adds a new compatibility kit (compatibility/repeat/*) and wires repeat settings into BaseCompatibility.cpp.

Hello Artem Pogorelov (@art-pogorelov) and thank you for your proposal! I'll have a look at your changes as soon as work allows. Sorry I didn't pick this up any time sooner. I just returned from a four week holiday.

One thing that is important is that the output is still valid in terms of 'cucumber messages'. I'll have to verify/cross reference this with the Cucumber maintainers.
