Subject: [PATCH] fix(android): block mention events when cursor is inside a
 finalized mention span
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Mirror iOS conflicting-styles behaviour in afterTextChangedMentions:
- After determining the candidate range [finalStart, finalEnd], scan for
  EnrichedInputMentionSpan across the full range (not just currentWord).
- If the span text matches the buffer, the mention is intact — call
  endMention() to suppress the event (fixes spurious mention list pop-up
  when a pre-filled @mention is loaded, e.g. in reply flows).
- If the span text has diverged (user edited inside it), remove the stale
  span and record mentionStart = spanStart so setMentionSpan can later
  replace the correct range when the user picks a new mention.
