CI lint:
- escape U+200B literals (staticcheck ST1018)

Real bugs (cursor[bot] + Copilot review):
- loop: ctx-cancel mid-cmd.Run() now classifies as OutcomeCancelled
  instead of being counted as a turn failure and tripping OutcomePaused
  after two consecutive cancels (#1)
- loop: save state before returning OutcomePaused so --continue resumes
  from a snapshot that includes the failing turn (#11)
- investigate fix: wrap context.Canceled as SilentError so Ctrl+C during
  the fix session doesn't print a cobra usage banner (#2)
- cmd: redact URL userinfo on the issue-link Source: line in both
  interactive and non-interactive paths (#5)
- issuelink: redact URL userinfo across gh stderr (not just argv) so a
  token in --issue-link cannot leak via the error path (#10)
- cmd: outcome-aware footer — "Investigation ended" + resume hint for
  paused/cancelled, "Investigation complete" + fix hint only for
  Quorum/Stalled (#6)
- cmd: validate maxTurns/quorum bounds after settings/flag merge so a
  hand-edited negative max_turns or oversized quorum errors cleanly
  instead of silently stalling (#7)
- issuelink: tolerate GitHub URL trailing segments (/pull/123/files,
  trailing slash) — the regex now anchors prefix and ignores tail (#13)
- picker: don't print "Saved investigate config" before persistence;
  moved to the caller after SaveLocal succeeds (#14)
- picker: guard pickerFormOverride with atomic.Pointer so parallel
  tests that swap the override don't race (#12)

Docs:
- settings/loop: fix stale "0 → 3" max_turns doc; default is 2 (#8/#9)
