feat(tools): converge on Claude and Codex modes

[Waishnav]

Converge the public tool modes to claude and codex, with Codex as the default. Remove the dedicated MCP grep, glob, and ls tools; each mode now uses its shell capability for search and inspection.

Documentation and exact tool-surface tests are updated with no legacy mode environment aliases retained.

Summary by CodeRabbit

📝 Walkthrough

Walkthrough

The PR changes tool mode selection to tools.mode, defaults to Codex, and adds Claude tools for file writing, file editing, and shell execution. Dedicated search and directory tools are removed. Documentation and tests reflect the new modes.

Changes

Tool modes and Claude surface

Layer / File(s)	Summary
Tool mode configuration contract src/user-config.ts, src/config.ts, src/config.test.ts, src/server.test.ts	Configuration now accepts claude or codex and defaults to codex. Tests use file-based mode configuration.
Claude tool implementations src/tool-surfaces/claude.ts	Claude registers workspace file writing, targeted editing, and bounded shell execution with validation, logging, diff statistics, and structured metadata.
Tool surface registration and tool inventory src/tool-surfaces/index.ts, src/tool-surfaces/types.ts, src/pi-tools.ts	The Claude surface replaces the standard registration. Dedicated search and directory tools are removed from the tool inventory and wrappers.
Tool mode documentation docs/configuration.md, docs/chatgpt-coding-workflow.md	Documentation describes Codex as the default, Claude configuration through tools.mode, shell-based search, and command-session handling.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to c5c25

This PR changes the default tool surface to Codex, removes dedicated search tools, and relies on local shell commands for inspection. Before merging, the documentation should clearly describe shell authority, reconcile the published tool inventories, and explain the removal of legacy environment settings so users do not receive an unexpected tool surface or misunderstand command permissions.

Poem

I hop through Codex fields so bright,
Claude tools write and edit right.
Shell commands run in bounded flight,
Old search tools fade from sight.
Config blooms with modes in light.

Greptile Summary

This PR replaces the legacy minimal/full tool surfaces with Codex and Claude modes, makes Codex the default, and moves mode selection into persisted user configuration.

• Adds the Claude write, edit, and shell tool surface.
• Removes dedicated grep, glob, and ls MCP tools.
• Updates configuration schemas, tests, and documentation for the new modes.
• Existing environment-based mode selection is removed without a compatibility or failure path.

Confidence Score: 4/5

The environment-configuration regression should be fixed before merging because existing deployments can silently start with the wrong client-facing tool surface.

loadConfig no longer reads the previously supported tool-mode environment variables, while the selected fallback changes the registered mutation and command tools without reporting the ignored configuration.

Files Needing Attention: src/config.ts

Important Files Changed

Filename	Overview
src/config.ts	Moves tool-mode selection to persisted configuration but silently drops the existing environment override.
src/user-config.ts	Adds strict persisted validation for the new claude and codex tool modes.
src/tool-surfaces/claude.ts	Preserves the former write, edit, and shell handlers under the new Claude surface.
src/tool-surfaces/index.ts	Maps the two supported modes to distinct registrations and instructions.
src/pi-tools.ts	Removes wrappers used solely by the discontinued dedicated search tools.
docs/configuration.md	Documents config.json mode selection but provides no migration warning for environment-based deployments.

Inline comments:
In `@docs/chatgpt-coding-workflow.md`:
- Around line 161-169: Update the earlier unscoped tool inventory in the
documentation to identify it explicitly as the Claude surface, or clearly
describe it as a union of mode-specific names. Keep the Codex default section
and its mode-specific lists authoritative, including the mappings represented by
the Claude and Codex tool-surface definitions.

In `@docs/configuration.md`:
- Around line 94-110: Update the tools.mode configuration documentation to
explicitly state that DEVSPACE_TOOL_MODE and DEVSPACE_MINIMAL_TOOLS are legacy
variables and no longer select the tool mode. Instruct users to configure
tools.mode in ~/.devspace/config.json instead, while preserving the existing
mode descriptions.

In `@src/tool-surfaces/claude.ts`:
- Line 34: Update both Claude shell descriptions in src/tool-surfaces/claude.ts
at lines 34-34 and 219-251 to state that runShellTool executes commands with the
local user’s authority and is not sandboxed; retain or enforce the no-write
restriction only if the tool is intended to be read-only. Review the related
shell description exposure in src/tool-surfaces/index.ts at line 9 and keep it
consistent with the updated Claude descriptions.
