assistant/codecompanion: rename strategies -> interactions

[SecBear]

Summary

codecompanion.nvim v19 renamed strategies to interactions (olimorris/codecompanion.nvim#2485). The nvf module still generates the deprecated strategies key in the Lua setup call.

Problem

codecompanion has a backwards-compat migration shim that detects strategies and converts it:

-- codecompanion config.lua:1274
if args.strategies then
  args.interactions = vim.tbl_deep_extend("force", vim.deepcopy(defaults.interactions), args.strategies)
  args.strategies = nil
end

When a user sets setupOpts.interactions (e.g. for adapter/CLI config) and the nvf module simultaneously generates setupOpts.strategies (for inline keymaps), the migration replaces the user's interactions table with defaults + strategies, silently discarding overrides like interactions.chat.adapter.

This causes the chat adapter to revert to the default (copilot), which fails with Copilot Adapter: No token found if the user does not have a GitHub Copilot token.

Fix

Rename the option tree from strategies to interactions so the generated Lua uses the current key and the migration shim is never triggered.

Sanity Checking

• I have updated the changelog as per my changes
• I have tested, and self-reviewed my code
• My changes fit guidelines found in hacking nvf
• Style and consistency
  • I ran Alejandra to format my code (nix fmt)
  • My code conforms to the editorconfig configuration of the project
  • My changes are consistent with the rest of the codebase
• If new changes are particularly complex:
  • My code includes comments in particularly complex areas — N/A, trivial rename
  • I have added a section in the manual
  • (For breaking changes) I have included a migration guide
• Package(s) built:
  • .#nix (default package)
  • .#maximal
  • .#docs-html — pre-existing: ndg lacks aarch64-darwin support
  • .#docs-linkcheck
• Tested on platform(s)
  • x86_64-linux
  • aarch64-linux
  • x86_64-darwin
  • aarch64-darwin

I don't have the means to test, but diff lgtm.

I thought auto-merge would get this...
