[chezsmithy]

Description

• In the latest release anthropic has enabled a new memory tool solution that allows local repository memory to be automatically updated based on internal model decisions.
• This PR implements the memory tool for the Bedrock provider, and OIA Bedrock adapter, as a tool.
• For the vscode and intelliJ extensions it's enabled as an experimental tool.
• for the CLI it's enabled as a default tool.

The tool is only enabled for the following models:

"claude-sonnet-4-5-20250929",      // Claude Sonnet 4.5
"claude-sonnet-4-20250514",        // Claude Sonnet 4
"claude-haiku-4-5-20251001",       // Claude Haiku 4.5
"claude-opus-4-1-20250805",        // Claude Opus 4.1
"claude-opus-4-20250514",          // Claude Opus 4

Creating a memory file in a new directory always fails: after creating the missing parent directory we throw `Path not found`, so fs.writeFile never runs. Drop the throw so the command can proceed.</violation>

After creating a missing directory, this branch still throws `Path not found`, so the create command always fails for new paths.</violation>

This enables the memory tool for any model containing “claude”, but the feature must be restricted to the specific allowlisted models from the PR description.</violation>
