v1.28.1

🚀 Updates

• Added caching around bun bun.lockb commands, instead of running them for every task.
• Updated and loosened identifier naming restrictions.
• Updated environment variable substitution to support different outputs when a variable is missing,
  based on a trailing flag syntax.
  • $FOO or ${FOO} - If variable is missing, keeps the original syntax (current default).
  • $FOO? or ${FOO?} - If variable is missing, replaces with an empty string.
  • $FOO! or ${FOO!} - Ignores variable substitution and preserves the syntax (without !).

🐞 Fixes

• Fixed an issue where an affected task with files that contain non-standard characters would fail
  to run because Bash expansion fails. We now quote file paths that contain *, $, +, and [].

⚙️ Internal

• Updated Rust to v1.81.
