Support Multiple Project Hashtags in Maniphest Search

[Timpan4]

Fixes #102

Changes

Core Functionality

• Match all project hashtags: maniphest search now matches against all configured hashtags/slugs for a project, not just the primary name
• Switched to project.query API: Uses project.query() instead of project.search() to access the full slugs array
• Deduplication: Automatically prevents duplicate results when multiple hashtags of the same project match a wildcard pattern

User Experience

• Case-insensitive matching: Works with any casing (e.g., devex, DevEx, DEVEX)
• Better error messages: Suggestions now show the matched slug in parentheses:

  ERROR - Project 'devx' not found. Did you mean: Developer-Experience (devex)?
  

• Primary name always searchable: Can search by project name OR any hashtag

Bug Fixes

• Fixed KeyError in CLI when running maniphest search (changed to use .get() instead of direct dict access)

Examples

# Before: Only primary name worked
$ phabfive maniphest search 'developer-experience'  # ✓
$ phabfive maniphest search 'devex'                 # ✗ Error

# After: All hashtags work
$ phabfive maniphest search 'developer-experience'  # ✓
$ phabfive maniphest search 'devex'                 # ✓
$ phabfive maniphest search 'dev-exp'               # ✓

# Clear suggestions with matched slugs
$ phabfive maniphest search 'devx'
ERROR - Project 'devx' not found. Did you mean: Developer-Experience (devex)?

Technical Details

• Uses project.query() API which returns all slugs in a slugs array
• Maintains backward compatibility - all existing functionality works unchanged
