feat(app): user manual — in-app reference and console help

…

- ZQCommandReference: one registry of every command (syntax, options,
  examples, notes) shared by the console and the app so they cannot
  drift; 35 commands across 10 categories
- console: 'help' lists the reference by category, 'help <command>'
  (abbreviations resolve too) renders the full entry
- app: Manual pane — searchable sidebar grouped by category, per-command
  pages (syntax/options/examples), and a 'How Metrika works' overview
  covering the command grammar, data handling, estimation conventions,
  the CPU/GPU planner, reproducibility, and user commands
- release plumbing: real team ID + notary keychain-profile NAME in
  release.sh (both configuration, not credentials, per the security
  conventions), manual Developer ID signing with hardened runtime,
  -skipPackagePluginValidation, DMG background art
- tests: help coverage test pins a manual entry for every implemented
  verb; UI smoke drives the Manual pane; 106 green

  t/F distributions accurate in the far tails
- ZQGPU: Philox4x32-10 reference RNG, counter-addressable bootstrap
- ZQEngine: session actor with use/save/gen/replace/drop/keep/summarize/
  regress/count/list/graph/bootstrap/set seed/xtset/log
