Fix disk budget for bounded workspaces

[chubes4]

Summary

• Treat absolute GiB disk-budget floors as unattainable on bounded ephemeral filesystems smaller than the floor.
• Keep percentage-based refusal/warning thresholds active so small runner workspaces are still protected from real pressure.
• Add smoke coverage for a WP Codebox-style 4 GiB workspace.

Verification

• php tests/smoke-worktree-disk-budget.php
• php -l inc/Workspace/WorktreeDiskBudget.php
• php -l tests/smoke-worktree-disk-budget.php

AI assistance

• AI assistance: Yes
• Tool(s): OpenCode (GPT-5.5)
• Used for: Diagnosed the Docs Agent runner failure, implemented the disk-budget threshold fix, and ran targeted verification for human review.
