fix: share one project-list build across callers; log slow builds - #36

Conversation
The deck abandons a project list after 150s and asks again on its next refresh, but the walk in the main process keeps going, so each retry stacked another full walk (58 repos of git, ~15.7k Codex rollout heads) on the first. Right after a boot SIHYEONG-4080 logged five 150s timeouts in a row (2026-10-12). Late callers now join the build under way, and a build slower than 20s is logged with its time summed per stage.

Problem
After 150s the deck stops waiting for a project list and asks again on its next refresh. The walk already running in the main process does not stop, so each retry started another full walk on top of it: 58 repositories of git, plus about 15.7k Codex rollout heads on SIHYEONG-4080. Right after a boot this showed up as five 150s timeouts in a row (2026-10-12, devdeck.log).
Change
projects:listkeeps one build in flight. Any caller that arrives while it runs, local or over Link, receives that same promise.warn, with time summed per stage (scan,git,sessions,cue). After the next slow boot, the log will show which stage was slow.QA
npm test: 1268 passed, 1 skipped. New test: a second call during a build returns the same promise, and a call after it lands builds fresh.🤖 Generated with Claude Code
