Six of the ten profiles rendered the same robot, because the map in
WelcomeScreen only knew four ids. The map moves to utils/profileIcons.js,
covers all ten — including the close pairs (`coder`/`developer`, the two
3D profiles) — and falls back to a hashed glyph from a pool rather than
one robot, so custom profiles differ from each other and stay stable
across renders. Covered by five unit tests.

Cards were ragged because each row took the height of its own content:
`grid-auto-rows: 1fr` makes every row as tall as the tallest card. A
fixed pixel height was the obvious alternative and is worse — "Server
Administrator" wraps on a phone. A three-line clamp on the desktop
description keeps one wordy profile from inflating every row.

The profile grid grows with the profile list, and on a phone it is taller than
the viewport once there are more than a couple of profiles. Nothing could
scroll: `#app` and `.app-main` both hide overflow, and `.welcome-screen` had no
overflow of its own, so the cards were clipped rather than pushed down.

The pane now scrolls, and its vertical centering is `safe center` — with a plain
`center` the overflow goes past the flex start edge and cannot be scrolled back
to. The sidebar toggle becomes `position: fixed` so it does not scroll away with
the content it sits above.

The profile was a duplicate on every axis we could measure. 22 of its 26
native tools were already developer's; the four it alone held —
reload_tools, create_mcp_server, test_mcp_tool, mcp_status — are 2.9 KB of
schema. Its model chain was the same seven models. Of its 14 KB prompt,
about 8 KB was copied verbatim from developer's (the whole `## Orchestration
model` block and everything from `## Editing policy` down), and most of the
remainder restated manuals/create_mcp_server.md, which already carried the
same ten-step workflow in more detail. It was not a specialisation, it was a
snapshot: `git log -S '"reload_tools"'` shows the tool lived in developer
until 61fa370 rewrote that profile around MCP and cut it off.

What kept it alive was a premise that no longer holds — that Navi's own
capabilities would be written as in-repo tools. They are MCP servers now,
and an MCP server is not a file in this repository with a life of its own:
it is an isolated process registered from mcp_servers.d/. So there is no
reason left for a profile whose only distinct feature is a toolset a general
developer profile can hold, and every reason to stop maintaining a second
prompt that drifts against the first.

- developer: + reload_tools, create_mcp_server, test_mcp_tool, mcp_status
  (24 → 28 native). Its sub-agent gains tool_manual, which is what it
  actually needed to reach the manual while writing a server — the previous
  tool_developer sub-agent had it, developer's did not.
- server_admin: + reload_tools only (24 → 25). Adding a third-party MCP
  server is something this profile does as often as developer does.
  Deliberately not to its sub-agent: reconnecting the MCP manager is a
  process-wide operation belonging to the main agent.
- The prompt and the manual took on what the deleted profile knew and
  create_mcp_server.md did not: reload_tools before the first test_mcp_tool
  (a freshly registered server is not connected, so the test fails and the
  iteration is wasted), the smoke test read by exit code — 124 means timeout
  killed a server still running, 0 means it exited on its own, usually a
  main() without parentheses — absolute command/cwd, mcp_status as discovery
  only, and the steps that stay inline instead of going to a sub-agent.

mcp_status and test_mcp_tool were built without an MCP manager, and their
fallback did `from navi.api.deps import _mcp_manager` — a name that does not
exist, so a live call raised ImportError rather than the intended "MCP
manager not available". The tools always passed a manager in tests, which is
why nothing caught it. Both now receive the manager at construction and fall
back to the live one lazily.

Sessions and profile_overrides are reassigned before the restart: agent.py
resolves the session's profile without a guard, so a deleted profile turns
every session that referenced it into an uncaught ProfileNotFound. Nothing
in the test suite pins the profile inventory, and profiles are read once at
import time — reload_tools does not re-read them — so this ships as a
restart, and the restart is also what makes it take effect.

- documentTitle: persistent nameById map — names for sessions beyond the
  loaded list page (list only holds ~30); map filled by fetches and
  loadSession meta, never wiped by later refetches
- createSession: placeholder inserted at the position the server list
  would give it (after pinned run, last_active desc) so refetch no
  longer visibly moves the new row
- SessionItem: skip empty .session-icons wrapper when no icons
- drawer breakpoint made exclusive (-sidebar-drawer 1280 -> 1279.98):
  viewport of exactly 1280px now gets the desktop sidebar

GnAvatar's :icon prop expects the full Phosphor class (e.g. 'ph ph-briefcase'),
not just the icon name. profileIcon() now returns 'ph ${cls}'.

GnAvatar render function ignores default slot content; it only reads
src, icon, and initials props. Fixes broken user avatar image display.

- ProfileBadge.vue: GnBadge → GnAvatar with profile initials
- AppSidebar.vue: custom user-avatar/img → GnAvatar with image or fallback initial
- WelcomeScreen.vue: profile-icon → GnAvatar with Phosphor icon + secondary variant

gnexus-ui-kit's iconNode() does not prepend the base `ph` class
when the icon string starts with `ph-`; it only keeps the string
as-is. All icon props must include the base class explicitly:
`icon="ph ph-sidebar"` instead of `icon="ph-sidebar"`.

Updated 15 icon bindings across 9 components.
