fix(tui): hide classifier sessions from session list (v0.2.11)

Every TJ_IN_CLASSIFIER-spawned `claude -p` creates its own session
JSONL in ~/.claude/projects/<hash>/, so the TUI session list grows
by one entry per ingested event. With auto-capture on, that turns
into hundreds of 1-message ghost sessions and real work gets buried.

Skip sessions whose first user message starts with the canned
classifier prompt prefix ("You classify chat chunks for an AI-coding-
agent task journal"). Backfill already drops them via its msg-count
threshold; the TUI didn't.

+### Fixed
+- TUI session list (`task-journal ui`) now hides classifier sessions.
+  Each `claude -p` invocation we make for classification creates its
+  own JSONL in `~/.claude/projects/`; without filtering, the TUI was
+  buried under hundreds of one-message ghost sessions all starting
+  with "You classify chat chunks for an AI-coding-agent task journal."
+  We now skip any session whose first user message begins with that
+  marker so only real conversations show up.
