fix(cmdScan): replace filepath.Glob ** with WalkDir + EM state run 11 — closes #52

[jpleva91]

Summary

• Fixes cmdScan() always reporting 0 Go files — filepath.Glob doesn't support ** recursive patterns in Go (POSIX glob only), so the pattern internal/**/*.go matched a literal dir named ** which never exists
• Replaces with filepath.WalkDir to recursively collect .go files under internal/
• Adds io/fs import required by the WalkDir callback's fs.DirEntry parameter
• Closes stale PR chore(squad): EM state update — run 9 (2026-03-31) #94 (run 9 state was already committed to master at 832cb58)

Code change

// Before (always 0 — ** is not supported by filepath.Glob)
goEntries, _ := filepath.Glob(filepath.Join(dir, "internal", "**", "*.go"))

// After (recursive, correct)
var goEntries []string
filepath.WalkDir(filepath.Join(dir, "internal"), func(p string, d fs.DirEntry, err error) error {
    if err == nil && !d.IsDir() && strings.HasSuffix(p, ".go") {
        goEntries = append(goEntries, p)
    }
    return nil
})

Test plan

• go build ./cmd/shellforge/ passes
• go test ./... — 25/25 pass (governance, intent, normalizer)
• shellforge scan in the repo root now correctly reports Go file count (was 0, now non-zero)

EM state

Run 11 — P2 bug sweep status:

• PR fix(main): log errors from run() helper — closes #51 #93 (fix bug: run() helper in main.go silently ignores command errors #51 run() errors): green, awaiting merge
• PR fix(scheduler): log WriteFile error + EM state run 10 — closes #65 #95 (fix bug: scheduler.go silently ignores os.WriteFile error when writing agent run log #65 WriteFile silent error): green, awaiting merge
• PR fix(cmdScan): replace filepath.Glob ** with WalkDir + EM state run 11 — closes #52 #96 (this PR — fix bug: filepath.Glob with ** in cmdScan never matches any Go files #52 Glob): pending CI

Updated: Anthropic API provider + native tool-use

This PR now includes the API-driven swarm architecture work:

New commits:

• 8790a99 — LLM Provider interface + Ollama implementation
• f332ef0 — Anthropic API provider with native tool-use (stdlib HTTP, zero deps)
• 12abca3 — Wire native tool-use into agent loop
• 9f55835 — --provider anthropic CLI flag
• efa140c — Fix tool_use block serialization in multi-turn conversations

Verified: 13 LLM tests + 4 agent loop tests pass. Live smoke test against Haiku successful.
