v0.5.0

Added

• quilt ui: the fleet dashboard in a browser. One command opens a live
  local web view of the same read-only fleet snapshot the terminal shows: who
  wrote what (per-actor line counts per file), active claims, blocked and
  queued actors, clashes, and the "Needs you" escalation queue. Local-only by
  design: binds 127.0.0.1, rejects non-loopback Host headers (DNS-rebinding
  guard), writes nothing, and falls back to a free port when 4747 is taken.
• Per-file authorship rows in the fleet view. quilt fleet --json (and
  /api/fleet in the UI) now includes files: every changed file with
  per-actor changed-line counts, unattributed line counts, and the file's
  worst overlap (none/adjacent/contended).
• Opt-in anonymous telemetry. Off by default; quilt setup asks once,
  on an interactive TTY only, and no answer means no. When enabled, Quilt
  sends anonymous usage counts (setup completions, sessions started,
  claim granted/denied/queued counts, commits, escalations) under a
  locally generated random id. Never code, file paths, repo names, actor
  ids, or commit messages; the hot hook path is never instrumented, and
  events post from a detached process so no command waits on the network.
  quilt telemetry on|off changes the decision any time;
  QUILT_TELEMETRY=0 force-disables per process. Documented in the
  README and docs/reference.md.
