Subject: [PATCH] fix: slash command suggestions trigger at any / in input, not
 only at start (#843)

Previously the regex ^\/(\S*)$ only matched when the entire text before
the cursor was a bare /command. Typing a slash mid-sentence (e.g.
"please run /he") produced no suggestions.

Changed pattern to (?:^|\s)(\/\S*)$  which matches / at the start of
input or after any whitespace. Also compute slashPos from match.index
instead of hardcoding 0, so insertCommandIntoInput replaces the correct
slice of the input when the command is mid-sentence.
