v0.3.8 — Complete topic creation guide

Expand the built-in English/Russian guide from six to eight pages, with separate pages for the topic-creation wizard, quick /new commands, and saved profiles.

• Cover every combination of optional server, profile and title, plus explicit directories, the directory: alias, quoted paths and multiword titles.
• Explain default selections, random/manual naming, exact configured IDs, typo handling and names that match a profile or server.
• Explain creation versus first prompt, supported reasoning, unavailable models/providers, profile changes, field cancellation and draft expiry.
• Add all four /reset forms, its profile-first argument order, directory rules when changing server, and pending-topic behavior.
• Clarify first-prompt delivery, queue commands, retrying after failures and stopping before closing a topic.
• Regenerate both eight-page PDF guides with expanded additional sections, readable command blocks and complete page layout. Preview generation now includes each actual guide page and its navigation.

Verified all 16 combinations of /new parameters with the real parser, wizard/direct routing, quoted directory aliases, title/name collisions, the four reset forms, and eight-page navigation in both languages. Telegram accepted all 16 native Rich Message pages with their buttons. Reviewed phone-sized previews and rendered PDFs visually; the temporary Telegram topic was deleted.

This release updates instructions and guide presentation; command behavior and launch settings remain unchanged.
