Subject: [PATCH] fix(ci): Taskfile YAML syntax error + staticcheck
 tagged-switch (jepa-fx-risk#19)

Taskfile.yml line 46 had an unquoted Go-template `{{.VAR}}` inside a YAML
flow sequence (`cmds: [...]`) -- the literal braces broke YAML parsing
outright ("did not find expected ',' or ']'"), so `task check` (and thus
CI's push-triggered check job) failed before running a single command.
A manual `workflow_dispatch` re-run passed because the autoresearch
workflow never calls `task check` at all -- unrelated path, not an
env/secret difference as first suspected. Quoted the string.

Also fixed a staticcheck QF1002 in internal/eval/var.go: a boolean
switch comparing the same variable (n1) in every case is a tagged
switch in disguise -- converted to `switch n1 { case 0: ... case n: ...
}`.
