docker/docker-agent v1.157.0 on GitHub

This release delivers several bug fixes across runtime token handling, model error recognition, and provider-specific behavior, along with a UI fix for text selection and a new build tag for embedders.

What's New

Adds docker_agent_no_hook_templates build tag, allowing embedders to drop text/template from the runtime to reduce binary size (relevant for WebAssembly targets)
Adds worktree: true opt-in for background agents to isolate concurrent tasks in separate git worktrees with independent checkouts, tools, and hooks
Validates structured output using google/jsonschema-go

Bug Fixes

Fixes tool calls cut off by the output-token limit being executed with truncated arguments instead of being retracted
Fixes llama.cpp context overflow errors not being recognized as token overflow, preventing auto-compact from triggering on Docker Model Runner
Fixes Gemini adapter not reporting MAX_TOKENS as a length stop or SAFETY stops as refusals, which could cause refused tool calls to execute and loop
Fixes sort -ofile and tree -ofile (option operands) being incorrectly classified as safe commands
Fixes server-side fallback token usage counting only the final attempt's tokens instead of all attempts, allowing token budgets to be exceeded
Fixes Google SDK endpoint precedence so that GOOGLE_GEMINI_BASE_URL and GOOGLE_VERTEX_BASE_URL environment variables are not overridden by injected catalog endpoints
Fixes OPENAI_BASE_URL not being considered when determining whether hosted (native) tool search should be disabled
Fixes double-click text selection to use Unicode word boundaries and grapheme-aware hit testing, highlighting, and clipboard extraction
Fixes runtime not preserving the raw thinking state of a length turn that retracts nothing
