fix: Move config to wiretap-api and launcher related api to wiretap-launcher

[skymansandy]

Fixes #53 — config classes and launcher helpers are now available in noop artifacts, allowing consumers to use install(WiretapKtorHttpPlugin) { … } and call enableWiretapLauncher() from commonMain without expect/actual workarounds when switching between real and noop.

What changed

New wiretap-api module — contains:

WiretapHttpConfig
LogRetention
HeaderAction
WiretapSseConfig
WiretapWsConfig
ExperimentalWiretapSseApi

Shared across real and noop artifacts via api(...).

New wiretap-launcher / wiretap-launcher-noop modules — launcher API extracted from wiretap-core.
Noop now exposes:

launchWiretapConsole()
enableWiretapLauncher()

Test plan

• Build all modules: ./gradlew build
• Dev variant: ./gradlew :composeApp:build
• Prod (noop) variant: ./gradlew :composeApp:build -PwiretapVariant=prod
• Android debug + release assemble
• iOS framework build for both variants
• Shake-to-launch still works in debug
