TimeTree Calendar 2.0.2

Brand and maintenance release on top of 2.0.1. It brings the new brand artwork
derived from the project banner and two export fixes.

Added

New brand images in custom_components/timetree/brand/, derived from the
project banner: icon.png/icon@2x.png carry the TimeTree wordmark, and
logo.png/logo@2x.png plus dark_logo.png/dark_logo@2x.png carry the full
banner. All six files keep the Home Assistant sizes (icon 256/512, logo shortest
side 256/512).
The project banner (ha_timetree.jpg) is shown at the top of the README.
Export attendee filter — the export can be restricted to events that include
at least one of the selected members. The member list is discovered dynamically
from your calendars, and a separate switch decides whether events without any
attendee are exported as well.

newest_wins is now applied to both_changed conflicts instead of leaving them
queued indefinitely.
Unmanaged-import fingerprints no longer raise a false conflict on every poll once
the initial import has settled.

Version bumped to 2.0.2 in manifest.json and in the README version badge.
Repository housekeeping: the stale ha2026_09_dev branch was removed, so main
is again the only branch.

Requires Home Assistant 2026.9 or newer. No configuration changes are needed.
