fix: render script command hints with active agent separator

[PascalThuet]

Summary

• Render user-facing script command hints with the active integration's invoke_separator.
• Update bash and PowerShell prerequisite guards in setup-tasks and check-prerequisites.
• Add regression tests for hyphenated agent command hints.

Why

Shared scripts were hardcoding dotted slash commands such as /speckit.plan, /speckit.specify, and /speckit.tasks.

That is correct for internal command IDs and dot-based integrations, but it is confusing for agents whose installed commands use invoke_separator: "-", where the resolvable slash command is /speckit-plan.

Implementation

The shared script helpers now read .specify/integration.json, resolve the default integration's stored invoke_separator, and format the displayed slash command accordingly. If state is missing or malformed, they fall back to the dotted form.

Validation

• git diff --check
• bash -n scripts/bash/common.sh
• bash -n scripts/bash/setup-tasks.sh
• bash -n scripts/bash/check-prerequisites.sh
• uv run pytest tests/test_setup_tasks.py -v
• uv run pytest tests/test_timestamp_branches.py -v

PowerShell was not available in the local environment, so the PowerShell regression tests were collected but skipped.

Pull request overview

Note

Copilot was unable to run its full agentic suite in this review.

This PR updates the Bash and PowerShell helper scripts to format user-facing “Run /speckit…” hints using the configured invoke_separator from .specify/integration.json, and adds tests to validate the updated messaging.

Changes:

• Add shared helpers to compute the invoke separator and format /speckit{separator}{command} consistently (Bash + PowerShell).
• Update setup/check scripts to use the formatted command in error/help hints.
• Extend integration tests to cover separator-aware messaging for both Bash and PowerShell.
