fix(types): fix ty python env resolution + triage discord adapter

The .venv directory (created by uv run) contained Python 3.13 with no
deps installed. ty auto-discovers .venv for module resolution, so it
could not find discord.py, aiohttp, etc., producing ~1000 false
"Module has no member" errors.

Removing the stray .venv makes ty fall back to the nix env (Python 3.12
with all deps installed). Also set python-version = "3.12" in
[tool.ty.environment] with a comment explaining why.

ty diagnostics: 4,422 -> 3,385 (-1,037)
Tests: 496 passed, 0 failed

fix(nix): use python311 in dev shell (matches requires-python floor)

Production venv still uses python312 (nixos-unstable default). The dev
editable venv now uses python311 — the requires-python floor (>=3.11) —
so ty type checking and local dev catch 3.12+-only syntax that wouldnt
