ui: expand Settings tab and refine tab-bar activity indicator

Turn the Settings tab into a navigable list (up/down cursor, Enter to
toggle, left/right to adjust) exposing the show-thinking, AGENTS.md,
CLAUDE.md, tool-orchestrator and telemetry toggles plus an
auto-compaction toggle and threshold slider. Generalize the config
feature read/write helpers and add getters/setters for the new flags and
the compaction settings.

Replace the Sessions-tab unread dot with a static secondary tint that
fires when a message arrives while the tab is unfocused, kept distinct
from the blinking alert shown when a session is waiting for input.

ui: bracket F-key tab labels and add tab-bar unread dot

Relabel the tab titles from "(F1)" to "[F1]" and render a
secondary-colored dot before the Sessions tab when any session has
unread messages, keeping the label width (and box) unchanged.

ui: add provider login and model picker, refresh status bar

Add an interactive login view and a model-picker tab backed by the providers
registry, with supporting tabs/command handling. Refresh the status bar with
context-aware shortcuts and a context-fill indicator, and render the
event.compacted notice. Includes the /compact, /fork, /trim, /goto, /copy
slash commands.
