feat: add --my-tasks mode for open assigned issues (#71)

List open Redmine issues assigned to the current (or overridden) user,
sorted by priority rank (P1..P5) then version due date with a stable id
tie-break. Renders an OSC 8 hyperlinked console table on stdout and a
counts/hours summary line on stderr; version due dates are fetched once
per unique version, unavailable versions degrade to an empty due date.

Also migrates the codebase to ruff 0.17.3 defaults (PEP 585/604
annotations, targeted noqa for intentional blind excepts and CLI root
logging). Behavior-neutral: 408 tests pass with -W error.
