fix: context bomb shows zeros for lines and language counts

[greynewell]

Problem

The context bomb output shows 0 lines and go (0), json (0) because the IR-to-ProjectGraph conversion doesn't correctly map the available API fields.

**Codebase:** 15 files · 51 functions · 0 lines
**Languages:** go (0), json (0)

Root cause (confirmed from raw API response)

The SupermodelIR response does not contain a line count field — TotalLines is simply not available.

For language counts, metadata.languages is []string (names only, no per-language file counts). The conversion currently builds map[string]int with all values set to 0, which renders as go (0), json (0).

The actual file/function counts live in summary (free-form map) and stats.nodeTypes:

"summary": { "filesProcessed": 15, "functions": 51, "primaryLanguage": null, ... }
"stats": { "nodeTypes": { "File": 15, "Function": 51, "Class": 52, ... } }
"metadata": { "fileCount": 15, "languages": ["go", "json"] }

Fix

1. TotalLines — remove from template (not in API), or derive from stats.nodeTypes if a line-count node type is ever added
2. Language counts — either:
   • Remove counts and just show names: go, json
   • Derive per-language file counts from stats.nodeTypes or by walking the graph nodes (nodes have a language property)
3. summary field — currently typed as a struct but the SDK defines it as map[string]any; should be unmarshalled accordingly to avoid silent zero-fills if field names change

Also noted

primaryLanguage came back null in the response for this repo — the language detection falls back correctly to metadata.languages[0].

Fixing context bomb zeros issue

• Gather context (read CLAUDE.md, find relevant files)
• Understand IR-to-ProjectGraph conversion code
• Fix TotalLines — removed from Stats struct and template (not in API)
• Fix language counts — changed Languages from map[string]int to []string, now shows names only
• Fix summary field — changed irSummary struct to map[string]any
• Update template languageList function for []string
• Commit and push changes
• Create PR link

Changes made

internal/api/client.go

• Removed irSummary struct; SupermodelIR.Summary is now map[string]any — reads filesProcessed, functions, and primaryLanguage dynamically via type assertions, preventing silent zero-fills if field names change
• Removed Stats.TotalLines (field doesn't exist in the API)
• Changed Stats.Languages from map[string]int to []string (API returns names only, no per-language counts)

internal/template/render.go

• Removed · {{.Graph.Stats.TotalLines}} lines from the codebase line
• Updated languageList to accept []string and render plain names (go, json instead of go (0), json (0))

Before:

**Codebase:** 15 files · 51 functions · 0 lines
**Languages:** go (0), json (0)

After:

**Codebase:** 15 files · 51 functions
**Languages:** go, json
