Problem
/vpn/logicalsrequires authentication since Proton made SRP mandatory, so the ProtonVPN provider cannot import at all. Closes #33.Fix

proton-core's default appversion ("Other") drew Proton's anti-abuse CAPTCHA demand (422/9001) on the first live login attempt, which fell through to the generic import-failed message. The session now sends the official Linux app's appversion/user-agent, and a CAPTCHA demand that still fires maps to its own failure message - it has no headless answer, so honesty is all the import can offer. Meant to be squashed into the SRP commit before merge. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>Impersonating the official app's appversion lied to the API operator and would go stale with every official release. The API accepts no third-party appversion strings, so proton-core's default ("Other") stands as the honest generic value, and the free-form user agent carries who we actually are. Whether "Other" is what drew the CAPTCHA demand was never established anyway - the 9001 mapping stays either way. Meant to be squashed into the SRP commit before merge. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>ef64c0bdrops the official-client impersonation added after the first live test: it lied to the API operator, undermined the abuse heuristics it was dodging, and would go stale with every official release — and the appversion-caused-the-CAPTCHA theory was never actually established. The session now uses proton-core's default appversion ("Other", the sanctioned generic) plus an honestaqomui (Linux)user agent. The 9001 CAPTCHA mapping stays. Both follow-up commits are meant to be squashed into the SRP commit before merge. If CAPTCHA demands persist with the honest identity, the next step is proton-core's human-verification flow (email code) as its own issue — not identity games.Verified live end to end (2026-08-24): SRP login with account credentials, CAPTCHA demand → solved link → token-carrying retry accepted, /vpn OpenVPN credentials fetched into the auth file, full logical list imported, tls-crypt certificate material written. Live testing surfaced and fixed along the way: hollow logicals (empty Servers arrays) in the real fleet, and the fleet's move from tls-auth to tls-crypt (template modernized against a current official config). README now documents the sign-in flow. Remaining branch commits are marked for squashing into the SRP commit before merge; suggested merge order: #148/#149/#151 first, then this rebased on top.
