Eliminates the race condition where a skill could be deemed available under one locale but then built/executed under a different locale after a language change. By merging the availability check into build() and returning null when the skill cannot be constructed, there is no longer a window between checking availability and building the skill where state can change. - Remove SkillInfo.isAvailable() abstract method - Change SkillInfo.build() return type from Skill<*> to Skill<*>? - Update all 15 SkillInfo implementations to return null if unavailable - Update SkillHandler to use mapNotNull for building skills - Update SkillSettingsScreen to use build() != null - Update test mocks and preview providers Addresses the root cause of the NPE in DicioTeam#412 at the architecture level.

- Remove buildSkillFromInfo helper, inline fallback build
- CalculatorSkill: accept operators as constructor param, no runtime !!
- JokeSkill: accept resolved locale as constructor param, no runtime !!
- TelephoneInfo/TimerInfo: use ?: return null pattern, no !!
- FlashlightInfo: remove @SuppressLint("NewApi")
- SkillSettingsScreen: source availability from enabledSkillsInfo via
view model instead of calling build() in composable
enabledSkillsInfo only contains skills that are enabled AND available. A skill disabled by the user would incorrectly appear as unavailable (greyed out). Now disabled skills are assumed available since we cannot determine availability without building them.
