docs(create-blogpost): retire character asides and name the voice tells
Update the series skill to match the de-asided posts and the audit
findings.
- Replace the "character asides as blockquotes" convention with an
explicit no-asides rule; both technical tangents and reaction beats
go inline in one first-person voice.
- Drop the now-obsolete blockquote clause from the hard paragraph rule.
- Expand the sound-like-a-person step with the five recurring tells the
series-wide audit surfaced, each with its fix.
- Add reaching-for-asides and the five tells to the anti-patterns.
