🐛 Check installed game version compatibility in mod install/update

[sakuro]

Summary

mod install and mod update selected MOD Portal releases without checking whether they're compatible with the installed Factorio game version, so an incompatible release could be selected and installed, leaving the game unable to load it.

Changes

• dependency.EffectiveBaseRequirement: derives the version requirement a release places on base — an explicit, required base entry in its dependency strings when present, otherwise synthesized as >= factorio_version.
• resolver.SelectLatest/SelectCompatible now take an installedBase *mod.MODVersion (nil skips the check) and filter out game-incompatible releases before picking the highest remaining version; Resolver.InstalledBase threads this through both the initial-spec and transitive-dependency selection paths.
• mod install/mod update now compute the installed base MOD's version and wire it through, so the game-version filter applies to both commands.
• mod download/mod sync are deliberately left unfiltered (out of scope for this issue), as is mod install <mod>@<exact-version> (an explicit version request is never filtered).

Test Plan

• New unit tests: dependency.EffectiveBaseRequirement, resolver game-compatibility filtering (SelectLatest/SelectCompatible/Resolver), CLI integration tests for mod install/mod update skipping incompatible releases and picking the highest compatible one.
• mise run default (test + e2e + vet + lint + fmt-check) passes.
