chameleon 2.56.0

Added

• Deep-work hires experts and manages its own worktree defensively. The
  skill's dig is now staffed, not solo: a "Hire experts (dispatch discipline)"
  section makes parallel subagents the default posture whenever two or more
  independent unknowns exist - read-only code scouts, version-pinned web
  researchers, and a fresh-context reviewer at verification - each dispatched
  with one owned question, the context it cannot discover alone, and a
  required answer shape. An expert's answer is input, not truth: every claim
  a decision rests on is verified first-hand before it enters the brief (new
  brief checkbox), and hired agents return evidence only - the brief decides.
  Step 3's external research gains a depth ladder (pinned-version docs, then
  the changelog across the exact version window, then the installed package's
  own source; a blog post is a lead, never a citation). Step 5's worktree
  setup was rewritten against empirically tested git behavior (both
  corrections refuted the guidance it was adapted from, live on git 2.50.1):
  detect an existing linked worktree by comparing
  git rev-parse --path-format=absolute --git-dir with the common dir (the
  raw-output comparison false-positives from a subdirectory, and a plain
  submodule does NOT produce the mismatch), use an existing worktree only
  when it is dedicated to the task, honor a user-declared placement above any
  tool default, never edit the user's .gitignore to make a placement work,
  and run a dependency-install + gate baseline before the first edit so
  Step 6 attributes new failures (inherited ones are reported, not fixed).
  Worktree infeasibility is triaged as a rule-2c hard dependency at Step 1,
  and the failure report covers the no-worktree-created case.

Note: the /chameleon-deep-work skill itself and the docs overhaul shipped in
v2.55.0; this release refines that skill.
