Rebuild the session page around structured transcripts.
- Session list: project groups start collapsed and remember the ones
expanded by hand; unchanged session files reuse their parsed metadata.
- Backend: all nine agents' transcripts parse into structured blocks
(text, thinking, tool call / result, image, event, step); the Codex
rollout parser is rewritten. New commands stream transcripts over a
Channel, serve full block content, image bytes and Finder reveal behind
validated content refs, and export a session as a Markdown file; a
transcript cache (8 entries / 96 MB) keyed by source fingerprints.
open_external now only allows http, https and mailto.
- Reader: turns laid out as prompt -> execution steps -> final reply, with
steps folded into a one-line summary, failures always shown, each
agent's native symbols and verbs, all / conversation / changes filters,
a conversation outline, in-session find, Markdown rendering (ported
from #6332), image lightbox and copy / export as Markdown.
- Review follow-ups: clippy, Codex 0.119-0.128 duplicate steps and late
failure status, Grok Build in-progress refresh, full arguments for long
shell commands, and shared block helpers across the parsers.
