[debug-certificate-manager] Fix home directory parsing for shells that echo commands

[Copilot]

Summary

When resolving the home directory in remote environments, shells that echo executed commands (e.g., set -x) cause output containing multiple instances of the marker strings. The parser was extracting from the first occurrence instead of the actual command output.

Details

Changed marker parsing from indexOf() to lastIndexOf() to extract from the final occurrence:

// Before: Extracts from first marker pair (echoed command text)
const startIndex: number = output.indexOf(markerPrefix);
const endIndex: number = output.indexOf(markerSuffix);

// After: Extracts from last marker pair (actual output)
const startIndex: number = output.lastIndexOf(markerPrefix);
const endIndex: number = output.lastIndexOf(markerSuffix);
if (startIndex !== -1 && endIndex !== -1 && endIndex > startIndex) {

Added validation that end marker follows start marker to handle malformed output.

Bumped the package version from 0.0.6 to 0.0.7 as version bumping for VSCode extensions is not automatic.

How it was tested

Created test scripts simulating shell echo scenarios:

• Verified indexOf() incorrectly extracts command text when shell echoes
• Verified lastIndexOf() correctly extracts home directory with echo enabled
• Verified backward compatibility with shells that don't echo
• Validated edge cases: unbalanced markers, multiple pairs

Impacted documentation

None.

Original prompt

In the debug certificate manager VSCode Extension, when looking for the home directory, some shells echo the command being executed before executing it. The output processor should therefore look for the last instance of the markers, rather than the first.

@copilot Also make a patch bump to the affected vscode extension package version, since version bumping of vscode extensions is not automatic.

Done. Bumped version from 0.0.6 to 0.0.7 in commit 7cd82c0.
