Upgrade BotKit to Fedify 2.0

Align BotKit with Fedify 2.0.3 and its modular package split.
Move vocab and runtime imports to @fedify/vocab,
@fedify/vocab-runtime, and @fedify/denokv.

Update the public API to match Fedify 2.0 by replacing
LanguageTag-based surfaces with Intl.Locale, using plain strings
for software.version, and removing parseSemVer(), SemVer,
LanguageTag, and parseLanguageTag() exports.

Refresh examples, docs, and CHANGES.md to reflect the new
package paths and API changes. Update lockfiles and manifests
for the new dependency graph.
