This resolves 19 test failures when running the test suite on macOS by converting the Bash 4.0+ uppercase parameter expansion ${word^^} to standard tr, and removing outer double quotes from command substitutions with heredocs to prevent syntax errors due to collapsed backslashes escaping single quotes in Bash 3.2.

Pull request overview
This PR improves macOS (BSD) Bash 3.2 compatibility for Spec Kit shell scripts by removing Bash 4+ parameter expansions and simplifying command-substitution quoting that can break in Bash 3.2.
Changes:
- Replaced Bash 4+ uppercase expansion (
${word^^}) withtr '[:lower:]' '[:upper:]'in branch-name generation logic. - Simplified several nested, double-quoted command substitutions in
update-agent-context.shto avoid Bash 3.2 parsing issues.

This resolves 19 test failures when running the test suite on macOS. There were two main issues: 1. Syntax errors in update-agent-context.sh caused by nested double-quoted command substitutions with tr '' character escaping, causing mismatched single quotes in Bash 3.2. 2. Bad substitutions in feature-naming scripts caused by using Bash 4.0+ uppercase parameter expansion ${word^^} which is unsupported in macOS default Bash 3.2. The fix replaces the expansion with standard tr '[:lower:]' '[:upper:]' and cleans up nested double-quoted assignments.
