v0.6.1: show project + session id in the UI header

[lroolle]

What

The page never said which run you were looking at — with two live UIs open or a folder of snapshots, telling them apart meant reading URLs out of pair rows. The header now carries the run identity:

• Project name — the directory cctrace ran in (basename, full path on hover). Injected as PageMeta by the live server and the exit-snapshot writer; cctrace view rebuilds pass no meta (the original cwd is not recorded in the trace) and degrade to session-only.
• Current Claude session id — extracted client-side from the pairs (newest live pair wins over prior-run merges), short form with the full id on hover, click to copy.
• Tab title becomes <project> · cctrace so multiple live UIs are tellable apart in the tab bar.

How

• extractSessionId joins the summarize.ts inline set (same toString() pattern as the rest — unit-tested once, identical live and in snapshots).
• META goes through jsonForScript, so a hostile cwd (</script> in a path) cannot break out of the script tag — regression-tested.
• getLiveHtml(port, meta) / renderSnapshot(pairs, meta) — both optional, {} keeps old behavior.

Tests

• 4 new tests (META embed, {} default, script-tag escape, inline presence): 146/146 pass.
• Smoke against the compiled binary: live page and exit snapshot both embed the project META; extractSessionId inlining survives bun build --compile; a stubbed-DOM run of the emitted page script renders cctrace · 365ad98d with the live pair winning over prior-run pairs.
