fix(deps): address critical and high severity security vulnerabilities (#827) 
* fix(deps): address critical and high severity security vulnerabilities

Bump vulnerable dependencies to patched versions across the monorepo:

Python (critical/high):
- fastmcp >=2.14.0 → >=3.2.0 (SSRF, path traversal, OAuth confused deputy, command injection)
- langchain-core >=1.2.11 → >=1.2.22 (path traversal in legacy load_prompt)

Python (low):
- cryptography >=46.0.5 → >=46.0.6 (incomplete DNS name constraint enforcement)
- pygments: add >=2.20.0 pin (ReDoS via GUID regex)

Node.js:
- serialize-javascript ^7.0.3 → ^7.0.5 (CPU exhaustion DoS)
- handlebars: add >=4.7.9 override (JS injection via AST type confusion)
- path-to-regexp: add >=0.1.13 override (ReDoS via route params)
- brace-expansion: add version range override (process hang/memory exhaustion)

Also adds type: ignore comments for FastMCP 2.x private attribute access that
ty now flags since FastMCP 3.x removed _tool_manager (guarded by try/except
and hasattr at runtime).

Regenerated all lock files across API, integrations, and tests.

* fix(deps): add ajv v8 scoped overrides for schema-utils and ajv-keywords

The global ajv ^6.14.0 override caused schema-utils and ajv-keywords to
receive ajv v6, but they require ajv v8 (for dist/compile/codegen). Add
scoped overrides to ensure these packages get ajv v8 while the global
override remains for packages that need v6.

* fix(tests): remove stateless_http from FastMCP() constructor calls

FastMCP 3.x no longer accepts stateless_http in the constructor. The
tests call tools directly without HTTP transport, so the parameter is
not needed.

* fix: update MCP tests for FastMCP 3.x _tool_manager removal

FastMCP 3.x removed _tool_manager. Tests now use
_local_provider._components for sync tool dict access and
mcp.list_tools() for async filtered tool listing.

* fix: resolve docusaurus build failures (ajv overrides + missing blog date)

- Remove global ajv ^6.14.0 override and scoped ajv-keywords/schema-utils
  overrides that caused webpack compilation errors manifesting as
  "Cannot read properties of undefined (reading 'date')" during SSR
  and "these parameters are deprecated" warnings. Natural version
  resolution (v6.12.6+ for v6 consumers, v8+ for v8 consumers) already
  satisfies the security fix (>= 6.12.3).
- Add missing date frontmatter to learning-capabilities blog post.

* chore: regenerate openapi spec and docs skill
