fix(skills): claude review items 4-7 (subscribe timeout, atomic_dump_yaml, hardcoded paths, lifecycle helper)

Item 4: --subscribe gains --timeout/--idle-timeout (idle default raised
        120s->600s, 0=disable); connect-error AND non-zero CONNACK now fall
        back to a polling loop. SKILL.md matches actual behaviour.
Item 5: --subscribe terminal-event YAML writes routed through
        lib.sh::atomic_dump_yaml (flock + schema-validate + .bak).
Item 6: removed hardcoded /home/godopu16/PuKi fallbacks in lib.sh,
        status.sh (x2) and reconcile.sh; paths now BASH_SOURCE-relative.
Item 7: lib.sh::delegate_publish_event helper consolidates the 4 duplicated
        lifecycle publish blocks; delete cwd|jid parser replaced with JSON.

Also: subscribe loop runs under the project venv python (paho) and delegates
all YAML work to atomic_dump_yaml on system python3 (PyYAML), since neither
interpreter has both modules — the original env_python path could never import
paho. Items 3 + 8 out of scope (per user). Verified on -L claude-phase4-test
(kill-server after).
