fix(embed): replace requests with httpx in profile_manager

- Use httpx.Client() instead of requests.get() for daemon health check - Update test mock to use httpx.Client instead of requests.get - Fixes ModuleNotFoundError in CI (requests not in dependencies)

 **Note:** All banks share a single database. Bank isolation happens within the database via the `bank_id` parameter passed to CLI commands.

+### Configuration Profiles
+
+Profiles let you maintain multiple independent configurations (e.g., different API endpoints, LLM providers, or projects). Each profile runs its own daemon on a unique port (8889-9888).
+
+**The Default Profile:**
+
+When you run `hindsight-embed configure` without specifying a profile, it configures the "default" profile. This uses the backward-compatible configuration at `~/.hindsight/embed` and runs on port 8888.
+
+**Creating Named Profiles:**
+
+```bash
+# Create a profile with single command
+hindsight-embed configure --profile my-app \
+  --env HINDSIGHT_EMBED_LLM_PROVIDER=openai \
+  --env HINDSIGHT_EMBED_LLM_API_KEY=sk-xxx \
+  --env HINDSIGHT_EMBED_LLM_MODEL=gpt-4o-mini
+
+# Create a profile interactively
+hindsight-embed configure --profile staging
+```
+
+**Using Profiles:**
+
+```bash
+# Option 1: Environment variable (recommended for apps)
+HINDSIGHT_EMBED_PROFILE=my-app hindsight-embed memory retain default "text"
+
+# Option 2: CLI flag
+hindsight-embed --profile my-app memory recall default "query"
+
+# Option 3: Set as active (persists across commands)
+hindsight-embed profile set-active my-app
+hindsight-embed memory recall default "query"  # Uses my-app profile
+
+# Clear active profile (revert to default)
+hindsight-embed profile set-active --none
+```
+
+**Profile Management:**
+
+```bash
+# List all profiles with status
+hindsight-embed profile list
+
+# Show active profile
+hindsight-embed profile show
+
+# Delete a profile
+hindsight-embed profile delete my-app
+```
+
+**Profile Resolution Priority:**
+1. `HINDSIGHT_EMBED_PROFILE` environment variable (highest)
+2. `--profile` CLI flag
+3. Active profile from `~/.hindsight/active_profile` file
+4. Default profile (lowest)
+
+**Note:** If a profile is specified but doesn't exist, the command will fail with an error. Profiles must be explicitly created using `hindsight-embed configure --profile <name>`.
+
 ### Files

+**Default Profile:**
 | Path | Description |
 |------|-------------|
-| `~/.hindsight/embed` | Configuration file |
-| `~/.hindsight/config.env` | Alternative config file location |
-| `~/.hindsight/daemon.log` | Daemon logs |
-| `~/.hindsight/daemon.lock` | Daemon lock file (PID) |
+| `~/.hindsight/embed` | Configuration file for default profile |
+| `~/.hindsight/daemon.log` | Daemon logs for default profile |
+| `~/.hindsight/daemon.lock` | Daemon lock file (PID) for default profile |
+
+**Named Profiles:**
+| Path | Description |
+|------|-------------|
+| `~/.hindsight/profiles/<name>.env` | Configuration file for profile |
+| `~/.hindsight/profiles/<name>.log` | Daemon logs for profile |
+| `~/.hindsight/profiles/<name>.lock` | Daemon lock file (PID) for profile |
+| `~/.hindsight/profiles/metadata.json` | Profile metadata (ports, timestamps) |
+| `~/.hindsight/active_profile` | Active profile name (when set with `profile set-active`) |
