**Problem**

The sbt launcher script used naive word splitting when parsing `.sbtopts` and `.jvmopts`, so arguments with spaces were split incorrectly. For example, `-J--add-modules jdk.incubator.concurrent` in `.sbtopts` and `-Dtest.key="value with spaces"` in `.jvmopts` were not passed to the JVM as intended.

**Problem**
After PR sbt#8730 (commit 921efce), inline comments in .jvmopts and .sbtopts files cause errors.
For example, `--add-opens=java.base/java.util=ALL-UNNAMED # comment` results in:
Error: Could not find or load main class #

The # and everything after it is now parsed as separate arguments instead of being stripped as a comment.

**Solution**
Update the sed command in outputConfigFileTokens() to strip inline comments (everything from # to end of line) before parsing tokens. Changed:
  sed $'/^\#/d;s/\r$//'
To:
  sed $'/^\#/d;s/\s*\#.*//;s/\r$//'

The new s/\s*\#.*// pattern matches optional whitespace + # + rest of line and removes it.

**Testing**
- Added integration test verifying inline comments are stripped from .jvmopts
- Manually tested with .jvmopts containing inline comments - no errors
- Full line comments (starting with #) still work correctly
