skillkit context undercounts tokens, misses @ imports in CLAUDE.md

[Railly]

Problem

skillkit context reports CLAUDE.md as ~1.3K tokens, but it doesn't resolve @path/file.md references. Those files get inlined by Claude Code at session start and count against every API call.

Example

My CLAUDE.md has 9 @ imports totaling ~1,386 lines (~12.5K tokens). Skillkit reports 3.9K total, real load is ~19K. That's a 5x undercount.

CLAUDE.md itself:     ~2,500 tokens
9 @ imports:          ~12,500 tokens  <-- invisible to skillkit
Skills metadata:      ~2,600 tokens
MEMORY.md (200 lines): ~1,500 tokens  <-- also not counted

Expected behavior

skillkit context should:

1. Parse @path/file.md lines in CLAUDE.md
2. Read and count tokens for each referenced file
3. Show them in the CLAUDE.MD BREAKDOWN section
4. Include MEMORY.md (~/.claude/projects/*/memory/MEMORY.md) in the total

Notes

Claude Code loads @ references eagerly at session start, not lazily. They're textual includes, like #include in C. Every referenced file is present in every API call for the entire session.
