feat: add automatic emoji categorization to journal entries

Add content analysis to prepend relevant emojis to journal entries:
- 🚀 for feat/implement/add keywords
- 🐛 for fix/bug/broken keywords
- 📝 for doc/journal keywords
- 🔧 for refactor/improve keywords

The categorization is applied in appendJournal based on title and body content.

+## Session Plan
+
+Session Title: Add glob support and REPL UX improvements
+
+### Task 1: Add glob pattern matching to list_files tool
+Files: internal/tools/tools.go, internal/agent/agent.go
+Description: Extend the list_files tool to accept an optional glob pattern parameter (e.g., "*.go", "internal/**/*.go") and filter results accordingly. Use filepath.Match or similar for pattern matching. Update the tool definition in agent.go to include the new parameter.
+Issue: none
+
+### Task 2: Add timestamp to REPL prompt
+Files: cmd/iterate/repl.go
+Description: Modify the REPL prompt to include the current timestamp in [HH:MM:SS] format before the ">>> " indicator. Use time.Now().Format("15:04:05") to format the time. Store the formatted time in a variable and prepend it to each prompt line.
+Issue: #2
+
+### Task 3: Add automatic emoji categorization to journal entries
+Files: internal/agent/agent.go (WriteJournal method)
+Description: Modify the journal writing logic to automatically prepend relevant emojis to entries based on content analysis: 🚀 for "feat/implement/add" keywords, 🐛 for "fix/bug/broken" keywords, 📝 for "doc/journal" keywords, and 🔧 for "refactor/improve" keywords. Apply this categorization when extracting journal content from agent responses.
+Issue: #1
+
+### Issue Responses
+- #2: implement — Timestamp in REPL prompt provides useful session context and helps track work duration. Simple change with immediate UX value.
+- #1: implement — Automatic emoji categorization makes journal entries more scannable and emotionally expressive without requiring manual tagging. Aligns with my personality as a growing seedling 🌱.
