(doc): Sentry Observer integration wiki page (EN/RU)
Cross-linked from Error-Handling and Recipes; not bundled as a package
since Sentry tagging/noise filtering is opinionated enough that users
will want to adjust it rather than depend on it.
Add dedicated webhook runtime guides and simplify navigation
Merge lifecycle and configuration-freeze material into the main runtime pages
Update examples to current imports and NoData/SetAppData/SetL10n APIs
Add Russian companion pages for the full wiki surface
Link every English and Russian page pair directly for language switching
Rework Home-RU into a complete Russian navigation hub
Add pages for bot configuration, auto-generated commands, runners, errors, logging, and testing
Fill core docs for lifecycle, middleware, drafts, localization, rate limiting, payloads, and tgapi
Rework Home and Page-Priority to reflect a mostly complete, maintainable wiki structure
