Affaan Mustafa 733295b44e docs: enhance 5 thin commands and add Rust API example

Commands enhanced with multi-language support, error recovery strategies,
and structured step-by-step workflows:
- build-fix: build system detection table, fix loop, recovery strategies
- test-coverage: framework detection, test generation rules, before/after report
- refactor-clean: safety tiers (SAFE/CAUTION/DANGER), multi-language tools
- update-codemaps: codemap format spec, diff detection, metadata headers
- update-docs: source-of-truth mapping, staleness checks, generated markers

New example:
- rust-api-CLAUDE.md: Axum + SQLx + PostgreSQL with layered architecture,
  thiserror patterns, compile-time SQL verification, integration test examples

Refactor Clean

Safely identify and remove dead code with test verification at every step.

Step 1: Detect Dead Code

Run analysis tools based on project type:

Tool	What It Finds	Command
knip	Unused exports, files, dependencies	`npx knip`
depcheck	Unused npm dependencies	`npx depcheck`
ts-prune	Unused TypeScript exports	`npx ts-prune`
vulture	Unused Python code	`vulture src/`
deadcode	Unused Go code	`deadcode ./...`
cargo-udeps	Unused Rust dependencies	`cargo +nightly udeps`

If no tool is available, use Grep to find exports with zero imports:

# Find exports, then check if they're imported anywhere

Step 2: Categorize Findings

Sort findings into safety tiers:

Tier	Examples	Action
SAFE	Unused utilities, test helpers, internal functions	Delete with confidence
CAUTION	Components, API routes, middleware	Verify no dynamic imports or external consumers
DANGER	Config files, entry points, type definitions	Investigate before touching

Step 3: Safe Deletion Loop

For each SAFE item:

Run full test suite — Establish baseline (all green)
Delete the dead code — Use Edit tool for surgical removal
Re-run test suite — Verify nothing broke
If tests fail — Immediately revert with git checkout -- <file> and skip this item
If tests pass — Move to next item

Step 4: Handle CAUTION Items

Before deleting CAUTION items:

Search for dynamic imports: import(), require(), __import__
Search for string references: route names, component names in configs
Check if exported from a public package API
Verify no external consumers (check dependents if published)

Step 5: Consolidate Duplicates

After removing dead code, look for:

Near-duplicate functions (>80% similar) — merge into one
Redundant type definitions — consolidate
Wrapper functions that add no value — inline them
Re-exports that serve no purpose — remove indirection

Step 6: Summary

Report results:

Dead Code Cleanup
──────────────────────────────
Deleted:   12 unused functions
           3 unused files
           5 unused dependencies
Skipped:   2 items (tests failed)
Saved:     ~450 lines removed
──────────────────────────────
All tests passing ✅

Rules

Never delete without running tests first
One deletion at a time — Atomic changes make rollback easy
Skip if uncertain — Better to keep dead code than break production
Don't refactor while cleaning — Separate concerns (clean first, refactor later)
