Refactor runtime capability probes

[chubes4]

Summary

• Add RuntimeCapabilities as the shared shell, binary, git, and remediation diagnostic surface.
• Route Environment, GitRunner, ProcessRunner, workspace bootstrap binary checks, and workspace capability reporting through the shared diagnostics.
• Preserve bootstrap's augmented PATH behavior while removing its direct exec command -v probe.

Dependency

• Stacked on Refactor process execution plumbing #567 because that process-runner PR is still open on GitHub.
• After Refactor process execution plumbing #567 lands, this PR can be retargeted/rebased to main without carrying the process-runner commit separately.

Verification

• php -l inc/Support/RuntimeCapabilities.php && php -l inc/Support/ProcessRunner.php && php -l inc/Support/GitRunner.php && php -l inc/Environment.php && php -l inc/Workspace/WorktreeBootstrapper.php && php -l inc/Abilities/WorkspaceAbilities.php
• php tests/smoke-environment-shell.php && php tests/smoke-workspace-git-capabilities.php && php tests/smoke-worktree-bootstrap.php && php tests/smoke-workspace-clone-ux.php && php tests/smoke-workspace-apply-patch.php && php tests/smoke-workspace-alias-tools.php && php tests/smoke-late-ability-registration.php && php tests/smoke-deferred-ability-registration.php
