v1.9.0

A focused release: a 12th target framework (pi.dev), and a full navigation
redesign that regroups the sidebar by task with collapsible sections and
landing pages — plus two follow-up fixes catching what the redesign missed.

Highlights

pi.dev (Pi Coding Agent) adapter

MyACE now compiles to 12 target frameworks. The new adapter was verified
against pi.dev's real docs rather than guessed: rules/agents fold into
AGENTS.md (Pi reads it hierarchically, the same mechanism OpenCode/Goose
use), skills map to .pi/skills/<name>/SKILL.md, workflows map to Pi's real
slash-command "prompt templates" (.pi/prompts/<name>.md), and model
configs merge into .pi/settings.json. MCP config is deliberately left
unimplemented — pi.dev/docs/latest/mcp 404s and no primary-source config
shape could be confirmed, so it's flagged as a follow-up rather than
fabricated.

Grouped, collapsible navigation

• The sidebar's flat 9-item list is replaced with four task-based,
  collapsible sections — Collections, Build, My Machine, and
  Settings — each collapsed by default and auto-expanding for whichever
  section contains the current page, with an indented sub-menu and a
  rotating chevron to indicate state.
• Every section now has its own landing "hub" page — a short description
  plus a card per page in that section, so a first-time visitor understands
  what a section is for before clicking into it.
• Settings is renamed from "Account", and its personal-account page is
  renamed Account (now at /settings/account) so the group and its own
  child page stop sharing a name now that Moderation and System are visible
  siblings.
• Every page that moved keeps its old top-level path alive as a redirect
  (/profiles, /compile, /import, /setup-audit, /sync,
  /orchestration(/build), /moderation, /admin/system all forward to
  their new grouped location) — nothing bookmarked before this release
  breaks.
• The Dashboard's subtitle and each hub's description were rewritten, and
  all four README screenshots (login, dashboard, collections, compile) were
  recaptured against the new UI.

Fixed

• The public, logged-out /welcome page still advertised "11 target
  frameworks" and omitted pi.dev from its list — missed by the adapter PR
  since it never touches that page.
• A documentation sweep found several frontend-route mentions
  (Orchestration Gallery, Compile page, Sync Dashboard, and four
  "Settings page" references) still pointing at pre-redesign paths.

Docs

• AGENTS.md rule 38 documents the new navigation structure: the single
  source of truth (frontend/src/lib/navigation.ts), the collapse/expand
  behavior, the hub-page pattern, and the full legacy-redirect table.
• README.md's adapter table, feature list, and repository-structure tree
  are all updated for pi.dev and the new frontend/src/pages layout.
