Update claude-bionify to 1.0.6

[abullard1]

Follow-up to #296. The vendored copy is at 1.0.1, five releases behind, and two of the
missing releases are Windows fixes that leave the plugin non-functional.

Anyone installing claude-bionify from this marketplace today gets:

Missing since	Effect
1.0.5	On native Windows the hook never starts. The python.org installer creates no python3.exe, and Windows ships a Microsoft Store placeholder of that name which exits 9009 without running Python. Hooks are spawned with no shell, so there was no fallback, and a failed MessageDisplay hook shows the original text without reporting an error. Silently inert.
1.0.3	Non-ASCII characters garble on Windows, so an em dash renders as mojibake.
1.0.4	Code blocks can be bolded as prose when Claude streams quickly.
1.0.6	/claude-bionify:status can report that nothing is being bolded when it is.
1.0.2	The skill no longer gives settings guidance when the plugin is absent.

This syncs plugins/claude-bionify/ to 1.0.6 and updates the version in both
.claude-plugin/marketplace.json and the plugin manifest.

Validation

• claude plugin validate ./plugins/claude-bionify --strict
• jq empty .claude-plugin/marketplace.json plugins/claude-bionify/.claude-plugin/plugin.json plugins/claude-bionify/hooks/hooks.json
• Upstream suite at 1.0.6: 127 passed, 2 skipped, 93.6% coverage
• The Windows fix was verified on a Windows 11 VM with python.org Python: before, exit 9009 and no output; after, the hook runs through the py launcher

Repo-level claude plugin validate . --strict reports 2 warnings, unchanged by this PR
(present on main before it).
