Fix 1872 rust scala lifetime

[squid-protocol]

Summary

Fixes #1872
Fixes #1853

This PR addresses the bug where Rust and Scala lifetime annotations (e.g. 'a, 'static, '_) caused function extraction to truncate signatures prematurely. Previously, the parser treated the single quote as the start of an unterminated string literal, causing it to consume the rest of the file until a closing quote or end of file was reached.

It also addresses #1853 where angle brackets used as math operators (<<, >>, >=, <=, ->, =>) or surrounded by whitespace incorrectly incremented bracket depth in generic languages, truncating signatures early.

Changes:

• Modified _count_top_level_args and _matching_paren_end in gitgalaxy/core/detector.py to explicitly recognize Rust and Scala lifetime patterns and skip them instead of entering string-parsing mode.
• Modified _count_top_level_args to intelligently skip angle brackets that are adjacent to math operators or whitespace, while perfectly preserving nested generic template closures (e.g. vector<vector<int>>).
• Regenerated the golden master audits and tree-sitter accuracy baselines to reflect the accurate structural metrics.
• Globally regenerated the tri_comparison_chart.svg across all languages to repair a previous overwrite that limited it to only Rust and Scala.
• Added a new Claude rule (.claude/rules/tri-comparison-chart.md) to enforce that the tri-comparison chart must always be regenerated globally using --all.
