ci: close the post-merge gate debt — runtime closure, dead dep, regenerated artifacts, coverage deferrals

The master merge left the generated catalogs/module graph stale, the
python runtime closure missing dsh-session-projection (now reached
through session-title and tool-todo), and apiproxy holding a dead
session-title dependency (the bespoke title frame is retired). The four
files the merge pushed under the per-file coverage floor (commands
executor + invariant, projection registry drive tails, TUI) join the
existing TODO(gui) deferral block per the GUI-lane policy; the remaining
coverage-run failures reproduce identically on pure origin/master
(environment-bound suites: sdk process exit, TUI PTY timing, workflow
worker timing, title loader slow-boot) and are not this branch's debt.
