Anchor the cli ignore rule to the repository root.
The unanchored cli rule also ignores new files under src/cli. Git can therefore omit new source files from normal git add operations. Change the rule to /cli so the root artifact remains ignored without hiding source additions.

Apply the output budget to the complete response.
If a tool returns many text blocks, each block receives its own getMaxOutputLength() allowance. The resulting content array can still contain far more text than the configured limit and reach the host that this change aims to protect. Share one remaining text budget across the mapped blocks, and cover a multi-block result in the MCP handler tests.

Restore the prior environment value.
If BASH_MAX_OUTPUT_LENGTH was set before these tests, afterEach deletes that value. Save the value before each test and restore it afterward, including its previously unset state. As per path instructions, review tests for “isolation of global/env/config state.”

Preserve well-formed text after truncation.
If max falls between the two code units of an emoji, slice(0, max) creates a lone surrogate. The earlier UTF-8 round-trip cannot repair that new invalid character. Sanitize the sliced prefix before appending the marker, and test a surrogate pair at the boundary.
