Short prefix / namespace matching

Description

Is your feature request related to a problem? Please describe.

Currently, users must type the exact task name or explicit aliases to run a task. In projects with large Taskfiles and namespaced tasks (e.g., api:openapi:export), typing full names is tedious during local development if explicit aliases haven't been manually defined for every command.

Describe the solution you'd like

Support Shortest Unique Prefix Matching (similar to Symfony Console or Git subcommand matching).

In the example a:o:e would match the task if unambiguous

Expected Behavior:

1. Unique match: If the provided input unambiguously matches a single task prefix (e.g., running task api:o when only api:openapiexport exists), Task should execute it immediately.
2. Ambiguous match: If the input matches multiple tasks, Task should halt execution and present a helpful suggestion list (similar to Symfony Console):

The prefix "doct" is ambiguous.
Did you mean one of these?
  - doctrine:database
  - doctrine:schema
  - doctrine:migrations

Maybe control this with a seeting, something like

options:
  prefix_matching: true
