fix(auth): update SameSite cookie policy description for clarity

- Expanded fetchSessionUser to include Bearer token from localStorage as a fallback for authentication when Secure cookies fail.
- Updated headers to conditionally include Authorization if a token is present.
- Ensured compatibility with the recent fix for the Secure cookie flag on private network connections.

+# QA Pre-commit All
+
+## Overview
+
+Executes all configured lefthook pre-commit-phase hooks to validate code quality, formatting, security, and best practices across the entire codebase. This skill runs checks for Python, Go, JavaScript/TypeScript, Markdown, YAML, and more.
+
+This skill is designed for CI/CD pipelines and local quality validation before committing code.
+
+## Prerequisites
+
+- Python 3.8 or higher installed and in PATH
+- Python virtual environment activated (`.venv`)
+- Pre-commit installed in virtual environment: `pip install pre-commit`
+- Pre-commit hooks installed: `pre-commit install`
+- All language-specific tools installed (Go, Node.js, etc.)
+
+## Usage
+
+### Basic Usage
+
+Run all pre-commit-phase hooks on all files:
+
+```bash
+cd /path/to/charon
+lefthook run pre-commit
+```
+
+### Staged Files Only
+
+Run lefthook on staged files only (faster):
+
+```bash
+lefthook run pre-commit --staged
+```
+
+### Specific Hook
+
+Run only a specific hook by ID:
+
+```bash
+lefthook run pre-commit --hooks=trailing-whitespace
+```
+
+### Skip Specific Hooks
+
+Skip certain hooks during execution:
+
+```bash
+SKIP=prettier,eslint .github/skills/scripts/skill-runner.sh qa-precommit-all
+```
+
+## Parameters
+
+| Parameter | Type | Required | Default | Description |
+|-----------|------|----------|---------|-------------|
+| files     | string | No     | --all-files | File selection mode (--all-files or staged) |
+
+## Environment Variables
+
+| Variable | Required | Default | Description |
+|----------|----------|---------|-------------|
+| SKIP | No | "" | Comma-separated hook IDs to skip |
+| PRE_COMMIT_HOME | No | ~/.cache/pre-commit | Pre-commit cache directory |
+
+## Outputs
+
+- **Success Exit Code**: 0 (all hooks passed)
+- **Error Exit Codes**: Non-zero (one or more hooks failed)
+- **Output**: Detailed results from each hook
+
+## Pre-commit Hooks Included
+
+The following hooks are configured in `.pre-commit-config.yaml`:
+
+### General Hooks
+- **trailing-whitespace**: Remove trailing whitespace
+- **end-of-file-fixer**: Ensure files end with newline
+- **check-yaml**: Validate YAML syntax
+- **check-json**: Validate JSON syntax
+- **check-merge-conflict**: Detect merge conflict markers
+- **check-added-large-files**: Prevent committing large files
+
+### Python Hooks
+- **black**: Code formatting
+- **isort**: Import sorting
+- **flake8**: Linting
+- **mypy**: Type checking
+
+### Go Hooks
+- **gofmt**: Code formatting
+- **go-vet**: Static analysis
+- **golangci-lint**: Comprehensive linting
+
+### JavaScript/TypeScript Hooks
+- **prettier**: Code formatting
+- **eslint**: Linting and code quality
+
+### Markdown Hooks
+- **markdownlint**: Markdown linting and formatting
+
+### Security Hooks
+- **detect-private-key**: Prevent committing private keys
+- **detect-aws-credentials**: Prevent committing AWS credentials
+
+## Examples
+
+### Example 1: Full Quality Check
+
+```bash
+# Run all hooks on all files
+source .venv/bin/activate
+.github/skills/scripts/skill-runner.sh qa-precommit-all
+```
+
+Output:
+```
+Trim Trailing Whitespace.....................................Passed
+Fix End of Files.............................................Passed
+Check Yaml...................................................Passed
+Check JSON...................................................Passed
+Check for merge conflicts....................................Passed
+Check for added large files..................................Passed
+black........................................................Passed
+isort........................................................Passed
+prettier.....................................................Passed
+eslint.......................................................Passed
+markdownlint.................................................Passed
+```
+
+### Example 2: Quick Staged Files Check
+
+```bash
+# Run only on staged files (faster for pre-commit)
+.github/skills/scripts/skill-runner.sh qa-precommit-all staged
+```
+
+### Example 3: Skip Slow Hooks
+
+```bash
+# Skip time-consuming hooks for quick validation
+SKIP=golangci-lint,mypy .github/skills/scripts/skill-runner.sh qa-precommit-all
+```
+
+### Example 4: CI/CD Pipeline Integration
+
+```yaml
+# GitHub Actions example
+- name: Set up Python
+  uses: actions/setup-python@v4
+  with:
+    python-version: '3.11'

+
+### Example 5: Auto-fix Mode
+
+```bash
+# Some hooks can auto-fix issues
+# Run twice: first to fix, second to validate
+.github/skills/scripts/skill-runner.sh qa-precommit-all || \
+.github/skills/scripts/skill-runner.sh qa-precommit-all
+```
+
+## Error Handling
+
+### Common Issues
+
+**Virtual environment not activated**:
+```bash
+Error: pre-commit not found
+Solution: source .venv/bin/activate
+```
+
+**Pre-commit not installed**:
+```bash
+Error: pre-commit command not available
+Solution: pip install pre-commit
+```
+
+**Hooks not installed**:
+```bash
+Error: Run 'pre-commit install'
+Solution: pre-commit install
+```
+
+**Hook execution failed**:
+```bash
+Hook X failed
+Solution: Review error output and fix reported issues
+```
+
+**Language tool missing**:
+```bash
+Error: golangci-lint not found
+Solution: Install required language tools
+```
+
+## Exit Codes
+
+- **0**: All hooks passed
+- **1**: One or more hooks failed
+- **Other**: Hook execution error
+
+## Hook Fixing Strategies
+
+### Auto-fixable Issues
+These hooks automatically fix issues:
+- `trailing-whitespace`
+- `end-of-file-fixer`
+- `black`
+- `isort`
+- `prettier`
+- `gofmt`
+
+**Workflow**: Run pre-commit, review changes, commit fixed files
+
+### Manual Fixes Required
+These hooks only report issues:
+- `check-yaml`
+- `check-json`
+- `flake8`
+- `eslint`
+- `markdownlint`
+- `go-vet`
+- `golangci-lint`
+
+**Workflow**: Review errors, manually fix code, re-run pre-commit

+
+## Notes
+
+- Pre-commit hooks cache their environments for faster execution
+- First run may be slow while environments are set up
+- Subsequent runs are much faster (seconds vs minutes)
+- Hooks run in parallel where possible
+- Failed hooks stop execution (fail-fast behavior)
+- Use `SKIP` to bypass specific hooks temporarily
+- Recommended to run before every commit
+- Can be integrated into Git pre-commit hook for automatic checks
+- Cache location: `~/.cache/pre-commit` (configurable)
+
+## Performance Tips
+
+- **Initial Setup**: First run takes longer (installing hook environments)
+- **Incremental**: Run on staged files only for faster feedback
+- **Parallel**: Pre-commit runs compatible hooks in parallel
+- **Cache**: Hook environments are cached and reused
+- **Skip**: Use `SKIP` to bypass slow hooks during development
+
+## Integration with Git
+
+To automatically run on every commit:
+
+```bash
+# Install Git pre-commit hook
+pre-commit install
+
+# Now pre-commit runs automatically on git commit
+git commit -m "Your commit message"
+```
+
+To bypass pre-commit hook temporarily:
+
+```bash
+git commit --no-verify -m "Emergency commit"
+```
+
+## Configuration
+
+Pre-commit configuration is in `.pre-commit-config.yaml`. To update hooks:
+
+```bash
+# Update to latest versions
+pre-commit autoupdate
+
+# Clean cache and re-install
+pre-commit clean
+pre-commit install --install-hooks
+```
