feat: Add Gitea MCP integration and project cleanup

## New Features
- **Gitea MCP Tools** (zero API cost):
  - gitea_read_file: Read files from homelab repo
  - gitea_list_files: Browse directories
  - gitea_search_code: Search by filename
  - gitea_get_tree: Get directory tree
- **Gitea Client** (gitea_tools/client.py): REST API wrapper with OAuth
- **Proxmox SSH Scripts** (scripts/): Homelab data collection utilities
- **Obsidian MCP Support** (obsidian_mcp.py): Advanced vault operations
- **Voice Integration Plan** (JARVIS_VOICE_INTEGRATION_PLAN.md)

## Improvements
- **Increased timeout**: 5min → 10min for complex tasks (llm_interface.py)
- **Removed Direct API fallback**: Gitea tools are MCP-only (zero cost)
- **Updated .env.example**: Added Obsidian MCP configuration
- **Enhanced .gitignore**: Protect personal memory files (SOUL.md, MEMORY.md)

## Cleanup
- Deleted 24 obsolete files (temp/test/experimental scripts, outdated docs)
- Untracked personal memory files (SOUL.md, MEMORY.md now in .gitignore)
- Removed: AGENT_SDK_IMPLEMENTATION.md, HYBRID_SEARCH_SUMMARY.md,
  IMPLEMENTATION_SUMMARY.md, MIGRATION.md, test_agent_sdk.py, etc.

## Configuration
- Added config/gitea_config.example.yaml (Gitea setup template)
- Added config/obsidian_mcp.example.yaml (Obsidian MCP template)
- Updated scheduled_tasks.yaml with new task examples

+# Obsidian MCP Server Configuration
+# ===================================
+# This file configures the external Obsidian MCP server integration.
+#
+# Setup:
+#   1. Copy this file:  copy config\obsidian_mcp.example.yaml config\obsidian_mcp.yaml
+#   2. Set your vault_path below
+#   3. Ensure Node.js 20+ is installed: node --version
+#   4. Restart the bot: python bot_runner.py
+#
+# The config file (obsidian_mcp.yaml) is gitignored to protect your vault path.
+# See OBSIDIAN_MCP_INTEGRATION.md for full documentation.
+
+obsidian_mcp:
+  # ---- Core Settings ----
+
+  # Enable or disable the Obsidian MCP integration
+  # Set to false to disable without removing the config
+  enabled: true
+
+  # Absolute path to your Obsidian vault directory
+  # This MUST be the root folder of your vault (contains .obsidian/ subfolder)
+  #
+  # Windows examples (use double backslashes OR forward slashes):
+  #   "C:\\Users\\username\\Documents\\Obsidian\\MyVault"
+  #   "C:/Users/username/Documents/Obsidian/MyVault"
+  #
+  # Linux/Mac example:
+  #   "/home/username/obsidian-vault"
+  #
+  # To use the bot's built-in zettelkasten vault (same files as custom tools):
+  #   "C:\\Users\\username\\projects\\ajarbot\\memory_workspace\\obsidian"
+  vault_path: "C:\\Users\\YOUR_USERNAME\\Documents\\Obsidian\\YOUR_VAULT"
+
+  # ---- Server Settings ----
+
+  server:
+    # Command to launch the MCP server
+    # Default: "npx" (downloads obsidian-mcp on first run)
+    # Alternative: "node" (if installed globally)
+    command: "npx"
+
+    # Arguments passed to the command
+    # The vault_path is appended automatically as the last argument
+    # Default: ["-y", "obsidian-mcp"]
+    #   -y = auto-confirm npm package installation
+    args: ["-y", "obsidian-mcp"]
+
+    # Server startup timeout in seconds
+    # Increase if npx is slow on first download
+    startup_timeout: 30
+
+  # ---- Permission Controls ----
+  # Control which operations the bot is allowed to perform.
+  # Disable categories to restrict the bot's access to your vault.
+
+  permissions:
+    # Read operations (safe, no changes to vault)
+    # Tools: read-note, search-vault, list-available-vaults, manage-tags
+    allow_read: true
+
+    # Write operations (creates new files or modifies existing ones)
+    # Tools: create-note, edit-note
+    allow_write: true
+
+    # Delete operations (permanently removes files)
+    # Tools: delete-note
+    # DISABLED by default for safety - enable only if you trust the bot
+    allow_delete: false
+
+    # Move/rename operations (changes file paths)
+    # Tools: move-note
+    allow_move: true
+
+    # Tag operations (modifies YAML frontmatter)
+    # Tools: add-tags, remove-tags, rename-tag
+    allow_tags: true
+
+    # Directory operations (creates new folders)
+    # Tools: create-directory
+    allow_directories: true
+
+  # ---- Safety Settings ----
+
+  safety:
+    # Require user confirmation before any write operation
+    # When true, the bot will ask "Are you sure?" before creating/editing notes
+    confirm_writes: false
+
+    # Create a backup copy before deleting a note
+    # Backup is saved to .trash/ in the vault root
+    backup_before_delete: true
+
+    # Maximum note content size in characters
+    # Prevents accidental creation of very large notes
+    max_note_size: 50000
+
+    # Directories the bot should never access or modify
+    # Paths are relative to the vault root
+    restricted_paths:
+      - ".obsidian"    # Obsidian app configuration
+      - ".trash"       # Obsidian trash folder
+      - ".git"         # Git repository data (if vault is version-controlled)
+
+# ---- Environment Variable Overrides ----
+# These environment variables override the YAML settings above.
+# Add them to your .env file if you prefer not to use YAML config.
