fix: properly quote CLI parameters to handle filenames with spaces

Browse Source 
Fixed parameter quoting in file operations and search tools to handle
filenames and values containing spaces correctly.

Root Cause:
- Obsidian CLI requires quoting values with spaces: name="My Note"
- Previous implementation used unquoted format: name=My Note
- Shell would split on spaces, breaking multi-word filenames

Solution:
1. Created formatParam() helper in src/utils/cli-helpers.ts
   - Always quotes parameter values: param="value"
   - Handles spaces and special characters safely

2. Updated file-operations.ts (8 tools):
   - All file/path/content/name parameters now quoted
   - create, read, append, prepend, delete, move, rename, open

3. Updated search.ts (1 tool):
   - query, path, format, limit parameters now quoted
   - Fixes searches with multi-word queries

Changes:
- Before: cmdArgs.push(\`file=${name}\`)
- After: cmdArgs.push(formatParam('file', name))

Files changed:
- src/utils/cli-helpers.ts (new): formatParam() and buildCmdArgs() helpers
- src/tools/file-operations.ts: Use formatParam() for all parameters
- src/tools/search.ts: Use formatParam() for all parameters

Impact:
- File operations now work with multi-word filenames
- Search queries with spaces now work correctly
- Content parameters with newlines/special chars handled safely

Known Issue:
- links.ts, tags-aliases.ts, properties.ts still need similar fixes
- These tools have additional structural issues (wrong command names)
- Will be addressed in follow-up commit

Build: 0 errors
