CTX release v0.0.15

Highlights

• Real-time, schema-valid streaming across all formats. Tree and content commands now share a single streaming
  pipeline that emits per-directory and per-file events, producing identical results for raw/JSON/XML while displaying
  output incrementally. (3f80e9d, e858f67, 5d8895b, da3f01a)
• Resilient tokenizer integration. Python helpers are autodetected via uv, sentencepiece models download on demand,
  and Claude model aliases map automatically so token counting “just works” without manual setup. (6af6a24, b8a6330,
  a7b3354, 979e156, 909039b)

Features ✨

• Added automatic uv invocation for helper scripts, including on-demand sentencepiece downloads for Llama models and
  self-contained Anthropic helpers. (6af6a24, b8a6330, a7b3354, 979e156)
• Tokenizer metadata is now surfaced in both tree and content summaries, with default summaries enabled for every run.

Improvements ⚙️

• Unified tree/content streaming walker captures file contents, streams chunks, and keeps JSON/XML renderers in sync
  while maintaining pretty-printed output. (3f80e9d, 5d8895b, da3f01a)
• CLI displays streaming progress while helpers count tokens and ensures trailing newlines so prompts resume cleanly.
  (509805a, d02f35c, e858f67)
• Fixed double counting in summaries and guaranteed done events even when traversal encounters errors. (9c511ab)

Fixes 🐛

• Removed spurious helper bootstrap output and normalized Anthropic payloads, preventing API failures. (7f09f1a,
  b8f3737, 2962cf9)
• Dropped stale llama warning suppression and ensured Anthropic helpers require a valid API key with helpful messaging.

Docs 📚

• Documented tokenizer model support, uv requirements, and the need to quote shell wildcards when excluding files.

Maintenance 🛠️

• Updated the toolchain to the latest Go release. (e15aa61)

Tests ✅

• Expanded streaming coverage, including helper-driven tokenization and end-to-end CLI fixtures for raw/JSON/XML output.

Upgrade notes: Ensure uv is on PATH; the CLI will fetch helper dependencies and models automatically. Provide an
ANTHROPIC_API_KEY when requesting Claude token counts.
