Sai Karthik 1e12102b92 CLI & Config changes to support disabling core tools (#35)
* feat(core): expose no-core-tools via CLI flag and config file

Allow users to disable all built-in core tools (bash, read, write,
edit, grep, find, ls, subagent) without recompiling, using a CLI flag,
environment variable, or .kit.yml config key.

Changes
-------
cmd/root.go
  - Declare noCoreToolsFlag bool alongside noExtensionsFlag.
  - Register --no-core-tools persistent flag with a descriptive help string
    listing the affected tools.
  - Bind the flag to viper key "no-core-tools" so the config file and
    KIT_NO_CORE_TOOLS env var also work (viper's standard precedence:
    CLI flag > env var > config file > default).
  - Set kitOpts.DisableCoreTools = viper.GetBool("no-core-tools") when
    assembling the Options struct in runNormalMode.

pkg/kit/kit.go
  - Add disableCoreTools local variable inside the viperInitMu-protected
    snapshot block, mirroring the noExtensions pattern exactly.
  - Resolve it as opts.DisableCoreTools || viper.GetBool("no-core-tools")
    so the SDK option and the viper key are both respected (OR semantics:
    either source can enable the flag).
  - Pass the resolved disableCoreTools into kitsetup.AgentSetupOptions
    instead of the raw opts.DisableCoreTools, completing the chain.

Usage
-----
  # CLI flag
  kit --no-core-tools

  # Environment variable
  KIT_NO_CORE_TOOLS=true kit

  # .kit.yml config file
  no-core-tools: true

  # SDK (unchanged, was already supported)
  kit.New(ctx, &kit.Options{DisableCoreTools: true})

The downstream path (kitsetup → agent.AgentConfig.DisableCoreTools →
agent.NewAgent nil-tool branch) was already in place and required no
changes.

* docs(readme): document no-core-tools flag, config key, and env var

Update three locations in README.md to reflect the new no-core-tools
control surface introduced in the previous commit:

CLI Reference → Global Flags
  Add --no-core-tools under the Extensions and tools section alongside
  --no-extensions, with a description listing the affected tools.

Configuration → Basic Configuration
  Add no-core-tools: false to the example .kit.yml block so users know
  it is a valid config file key (equivalent to the CLI flag and env var).

Go SDK → With Options
  Expand the DisableCoreTools comment to note that the same behaviour is
  also available via --no-core-tools, KIT_NO_CORE_TOOLS, and
  no-core-tools: true in .kit.yml, making the cross-surface relationship
  explicit for SDK consumers.
