Add /test-profile slash command for Claude Code integration

Add `/test-profile` slash command to enable interactive profiling workflow
through Claude Code interface with the Go-based test profiling tools.

The command provides access to:
- start/stop: Background profiling daemon workflow
- run: Automated test execution with profiling
- analyze: Generate analysis reports from collected profiles
- compare: Compare two test runs side-by-side
- collect: One-time profile snapshots

Documentation includes configuration, output structure, and implementation
steps for the Go-based CLI tool located in hack/tools/test-profiling/.

+---
+
+# Test Profiling
+
+Profile memory and CPU usage during e2e tests using the Go-based `bin/test-profile` tool.
+
+## Available Commands
+
+### /test-profile start [name]
+Start background profiling daemon. Collects heap/CPU profiles from operator-controller and catalogd every 10s.
+- Auto-stops after 3 consecutive collection failures (e.g., cluster teardown)
+- Use with any test command: `make test-e2e`, `make test-experimental-e2e`, etc.
+- Follow with `/test-profile stop` to generate analysis
+
+**Example:**
+```bash
+/test-profile start baseline
+make test-e2e
+/test-profile stop
+```
+
+### /test-profile stop
+Stop profiling daemon and generate analysis report. Cleans up port-forwards and empty profiles.
+
+### /test-profile run [name] [test-target]
+Automated workflow: start test, profile until completion, analyze.
+- Default test-target: `test-e2e`
+- Other targets: `test-experimental-e2e`, `test-upgrade-e2e`, etc.
+
+**Example:**
+```bash
+/test-profile run baseline test-e2e
+```
+
+### /test-profile analyze [name]
+Analyze existing profiles in `test-profiles/[name]/`. Generates markdown report with:
+- Memory/CPU growth patterns
+- Top allocators
+- OpenAPI, JSON, and cache hotspots
+
+### /test-profile compare [baseline] [optimized]
+Compare two test runs. Outputs to `test-profiles/comparisons/[baseline]-vs-[optimized].md`
+
+### /test-profile collect
+One-time snapshot of heap/CPU profiles from running pods. Saves to `test-profiles/manual/`
+
+## Implementation Steps
+
+When executing commands, I will:
+
+1. **Build tool**: `make build-test-profiler` (builds to `bin/test-profile`)
+2. **Execute command**: `./bin/test-profile [command] [args]`
+3. **For start/stop workflow**: Monitor daemon logs, handle errors gracefully
+4. **For run command**: Start test in background, monitor progress, analyze on completion
+5. **For analysis**: Present key findings from generated markdown reports
+
+## Configuration
+
+Environment variables (defaults shown):
+```bash
+TEST_PROFILE_COMPONENTS="operator-controller:olmv1-system:operator-controller-controller-manager:6060;catalogd:olmv1-system:catalogd-controller-manager:6060"
+TEST_PROFILE_INTERVAL=10           # seconds between collections
+TEST_PROFILE_CPU_DURATION=10       # CPU profiling duration
+TEST_PROFILE_MODE=both             # both|heap|cpu
+TEST_PROFILE_DIR=./test-profiles
+TEST_PROFILE_TEST_TARGET=test-e2e
+```
+
