v0.1.27 — bump nlk to v0.5.2 (strip code-span fix)

fix: bump nlk to v0.5.2 (strip ignores in inline code spans)

Picks up the strip fix where <tag> matches inside markdown
inline-code spans are no longer treated as unclosed thinking
blocks. The symptom surfaced during v0.1.26 verification when
the user asked "THINK というタグについて教えて" — the local LLM's
reply was truncated mid-explanation as soon as it tried to write
the literal <think> reference inside backticks.
