claude: live-tail terminal sub-card in expanded Bash cards (T-325, UI)

Browse Source 
Wire the detection + follower core into the Bash tool card. A Bash card
with a follow intent (`tail -f …`) gains a "live tail" segment below the
result: an embedded read-only TerminalView fed by FileTailFollower on the
file the command follows, resolved against the open workspace.

Lazy lifecycle for free: the collapser builds its children only when
expanded (clide_collapser_card.dart), so _BashLiveTail starts the follower
in didChangeDependencies on expand and stops it in dispose on collapse —
no follower runs until the card is expanded. No resolvable file-backed
source → a muted "no independent source to follow" note, never an empty
terminal. The workspace root comes from kernel.project.current, so no new
plumbing through the conversation widget tree.

Tests: a tail Bash card surfaces the segment (+ the muted note when no
project/source); an ordinary `ls` card gets no segment; the segment only
builds on expand.
