v5.0.0-alpha.3.4

alpha.3.4: connection modes, CLI startup, #goto, portable, parser fix

Connection
- Connect dialog: Direct SGE / Lich proxy mode dropdown; profile remembers the mode
- CLI startup parameters --host/--port/--profile/--mode (bare host:port = Lich proxy)
- Per-profile data directory + folder picker
- Portable mode: genie5.portable marker + writable-location guard
- TLS SGE auth (port 7910, pinned certificate; plaintext fallback)

Mapper / quality of life
- #goto / #go2 command — attended, roundtime-gated walk by id, label, or title
- Default numpad movement macros seeded on a profile's first run
- Open Scripts Folder opens the folder the script engine actually loads from
- Auto-walk unfocus pause is now opt-in (off by default)

Parser
- Recover server-merged game text appended to held-item updates instead of dropping it

Docs: policy posture reframed around the DR Scripting Policy; alpha.3.4 notes.
Update channel now defaults to beta so prerelease builds are visible in-app during alpha.

Closes #6, #37, #38, #39, #41
