v0.10.0

Added

• plane drift groups each section by the observing adapter, states a shared
  message once on the group header, and packs the bare ids into columns sized
  per column. A 16-item section reads as four rows instead of sixteen, and
  nothing is truncated where it used to be. The grouping comes from the id's
  own adapter/native_id shape, so every adapter, present and future, gets it
  without the renderer naming any of them.

Changed

• The footprint conventions the example instance recommends no longer include
  macOS's ~/Library/Application Support. Measured on a real machine, 37 of
  its 79 entries were the system's own and most of the rest were desktop apps
  and derived caches of tools a package manager already governs, so the root
  produced rows nobody can declare, apply, or remove. docs/footprint.md
  records why the alternative, teaching the tool to filter the OS's own
  directories back out, was rejected: that filter would key on names its
  subject chooses.

Fixed

• The footprint noise defaults skip shell completion caches
  (.zcompdump, .zcompdump-<host>-<version>), found by running the
  adapter against a real machine. Two rules now bound what ships as a
  default: a pattern must match something real on a scanned machine, and no
  pattern may match a directory where software wires itself to run at login
  (systemd, autostart, LaunchAgents), which a test enforces.
