Patrick Buckley 3b9de67e8c refactor(session): extract think-tag splitting into ThinkTagSplitter
The interactive chunk consumer's _flush_text/_drain_pending closure pair
carried the partial-tag carry buffer and in-think state inline. The
tag-scanning half moves to turnstone/core/streaming_text.py as a
standalone ThinkTagSplitter (carry buffer, in_think state, earliest-
index tag selection, MAX_TAG_LEN safe-flush); dispatch and accumulation
stay in the session behind the emit callback, and out-of-band
transitions (reasoning_delta path, tool-call starts, cancellation)
read/write splitter.in_think and flush_pending() where they previously
touched the closure locals.

Pure move: table-driven pins covering partial-tag buffering across
chunk boundaries, the safe-flush margin, open/close tag precedence,
in_think transitions, and reasoning-vs-content dispatch were written
against the closure implementation and pass unchanged against the
extracted class — byte-identical emitted text, identical UI callback
ordering. The session-level _THINK_*/_MAX_TAG_LEN class constants fold
into the class.
