fix(openclaw): normalize better-sqlite3 bootstrap paths on Windows

[fancyboi999]

Description

This fixes the Windows false negative in the OpenClaw plugin bootstrap for better-sqlite3.

Problem solved:

• The runtime entry used new URL(import.meta.url).pathname and a raw startsWith check to decide whether better-sqlite3 resolved inside the plugin directory.
• On Windows, pathname can produce /C:/... while require.resolve(...) returns C:/..., so the same path is incorrectly treated as outside the plugin dir.
• That false negative incorrectly triggers the rebuild path and eventually surfaces as better-sqlite3 native module not found even when the module is already installed.

Implementation approach:

• Extract the runtime bootstrap into a dedicated helper so the entry-point path logic is independently testable.
• Convert import.meta.url to a real filesystem path with fileURLToPath(..., { windows: true }) on Windows.
• Replace the fragile string-prefix check with a path relationship check based on path.relative(...).
• Keep the existing auto-rebuild fallback, but run it from the normalized plugin directory.
• Reuse the resolved plugin directory when reading package.json, removing the previous dependency on __dirname semantics.

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Refactor (does not change functionality, e.g. code style improvements, linting)
• Documentation update

Coverage added in this PR:

• Windows import.meta.url to filesystem path conversion
• Windows path containment with mixed slash/case forms
• Guard against sibling-prefix false positives
• Rebuild retry path after an initial outside-plugin resolution

Notes:

• tests/plugin-impl-access.test.ts showed an existing local runner-exit hang when run standalone in this environment. This PR does not change plugin-impl.ts, and the new bootstrap tests cover the runtime path logic introduced here.

Pull request overview

Fixes a Windows-specific false negative when checking whether better-sqlite3 resolved within the OpenClaw plugin directory by normalizing path handling and refactoring the bootstrap logic into a testable helper.

Changes:

• Extracted better-sqlite3 bootstrap/load/rebuild logic into src/runtime/sqlite-bootstrap.ts.
• Replaced string-prefix path checks with a path.relative(...)-based containment check.
• Added unit tests covering Windows path normalization and rebuild retry behavior; updated plugin entry to use the new helper.
