Add profile_id support to list_tools ...

ListToolsTool now accepts an optional `profile_id` parameter. When
provided, it returns only the tools enabled for that specific profile
(enabled_tools + user tools + resolved MCP tools). This helps the agent
preview what a profile can do before switching.

- Updated ListToolsTool.execute() with profile-aware filtering
- Patched _profile_registry in build_default_registries
- Patched _mcp_manager in main.py startup loop

Fix gnexus-book MCP instructions and add old-format fallback in tool executor ...

- Updated mcp_servers.json gnexus-book instructions to use mcp:gnexus-book:
  prefix instead of the old mcp_gnexus-book_ format.
- Added fallback in tool_executor.py for old underscore format
  (mcp_server_tool → mcp:server:tool) so transitional models still work.
- Added unit test for the old-format fallback.

Generate session titles in the user's language ...

Adds "Respond in the same language as the user's messages" to the
session title generator system prompt so titles match the conversation
language instead of defaulting to English.

Fix profile MCP server groups to use group names instead of tool names ...

Profile configs were listing individual tool names (web_view, http_request)
in mcp_servers.navi-web instead of group names (browse, request). This caused
resolve_group() to return empty results, so MCP tools never appeared in the
profile's resolved tool list.

Also fixes modeler_3d stale tool references in system_prompt.txt.

Fix agent.py _tool_list to use colon-delimited MCP names ...

The main registry and API routes were migrated, but Agent._tool_list
still built names with the old underscore format. This meant MCP tools
were silently dropped from the tool list passed to the LLM, causing
"tool not found" when the model correctly called mcp:server:tool names.

Also updates stale docstring in McpTools.

Rename MCP tools to mcp:server:tool format and restore human-readable names ...

- Core naming: mcp_server_tool → mcp:server:tool (colon-delimited)
- navi-web tools: search/view/request → web_search/web_view/http_request
- navi-3d tools: compile_scad/render_stl/lint_scad (unchanged names)
- Updated all profile configs, system prompts, docs, manuals, tests
- Added new lint_scad.md manual
- Fixed modeler_3d prompt stale references (scad_lint, model_3d, render_3d)
- All 240 tests pass

Clean up remaining web_search / web_view / http_request references ...

- Deleted stale source files: navi/tools/web_search.py, web_view.py,
  http_request.py (no longer imported or registered).
- Updated system_prompt.txt in all profiles (secretary, server_admin,
  discuss, modeler_3d subagent) to reference mcp_navi-web_* tool names.
- Updated key_tools in developer, secretary, server_admin config.json.
- Updated docs (tools.md, profiles.md, api.md) to reflect MCP migration.

Tests: 240 passed.

Rename navi-web MCP tools and compact search output ...

- web_search → search, web_view → view, http_request → request
  This removes the redundant 'web' prefix from tool names in the
  navi-web MCP server, making them cleaner: mcp_navi-web_search etc.

- Compact search output: output string now contains only
  [Source] + [N] Title — URL, without duplicating the body snippet.
  Full results with body/description remain in metadata for
  programmatic use.

- Updated mcp_servers.json groups and all profile configs.

Tests: 240 passed.

Migrate 3D modeling tools to standalone MCP server navi-3d ...

- Tools: compile_scad, render_stl, lint_scad
- Session-scoped path resolution via SESSION_FILES_DIR env
- Anti-escape validation for security
- Includes tests/unit/test_scad_analyze.py

Phase 2 — Remove from Navi core:
- Deleted navi/tools/{model_3d,render_3d,scad_lint}.py
- Removed from registry.py builtins and navi/tools/__init__.py
- Updated pyproject.toml testpaths to exclude mcp-servers/

Phase 3 — Wire into Navi config:
- Added navi-3d block to mcp_servers.json (SSE on :8002)
- Updated modeler_3d profile: mcp_servers + updated system_prompt
- All old tool names replaced with mcp_navi-3d_* equivalents

Auto-inject relevant memory facts into LLM context on every user turn. ...

Semantic search against the vector memory store runs in parallel with
context provider collection. Number of injected facts scales with
message length (1–3) to reduce noise on short queries. Guardrails:
min length gate, per-turn deduplication, and structured logging at
info level for observability.

Remove dead LLMBackend.stream() method ...
