* feat(envelope): wire up ConfidenceFactors and CacheInfo in FromProvenance

v8.0: Actually populate the confidence factors and cache info
that were added in #71 but not wired up.

Changes:
- generateConfidenceFactors() creates factors from backend contributions
- Each backend gets a factor with status (available/unavailable) and impact
- SCIP backend has higher impact (+0.3/-0.2) than other backends (+0.1/-0.05)
- Repo state (clean/dirty) also included as a factor
- CacheInfo populated when CachedAt is present in provenance
- Added ConfidenceFactor type and Factors field to Confidence struct
- Added CacheInfo type and Cache field to Meta struct
- Comprehensive tests for all scenarios

* feat(mcp): add v8.0 compound tools for AI workflow optimization (#77)

Add 5 compound tools that reduce AI tool calls by 60-70%:

- `explore`: Area exploration (file/dir/module) with key symbols, dependencies, hotspots
- `understand`: Symbol deep-dive with ambiguity handling and grouped references
- `prepareChange`: Pre-change impact + risk assessment with test coverage info
- `batchGet`: Retrieve multiple symbols by ID in one call (max 50)
- `batchSearch`: Multiple symbol searches in one call (max 10)

These compound tools coexist with granular tools. Granular tools remain for specific queries; compound tools optimize AI workflows by aggregating multiple queries.

Files:
- internal/query/compound.go: Core implementation
- internal/mcp/tool_impls_compound.go: MCP handlers
- internal/mcp/tools.go: Tool definitions
- internal/mcp/presets.go: Added to core preset (19 tools)
- internal/query/compound_test.go: Tests

* feat(cli): add global configuration and project switching

Implement a two-tier configuration model for CKB that separates global
state from project-specific state. This allows users to run `ckb status`
from anywhere without creating local `.ckb/` folders, and easily switch
between registered projects.

New commands:
- `ckb use [name]` - Switch active repository or show current
- `ckb use --list` - List available repositories
- `ckb repos` - Alias for `ckb repo list`

Changes:
- Add active repo resolution order: env var > flag > CWD > default
- Update `ckb init` to register repos in global registry and set as active
- Update `ckb status` to show global status when no active repo
- Update engine_helper to use resolved repo instead of just CWD
- Add symlink resolution for path matching (macOS /var -> /private/var)

Key behaviors:
- Running `ckb status` in ~/Downloads shows registered projects list
- Running `ckb status` with an active repo shows detailed status
- No `.ckb/` folders created unless running `ckb init`
- CWD auto-activates if it matches a registered repo

  - internal/federation, internal/identity

- Delete internal/logging package

This is part of the v8.0 logging improvements to standardize on Go's
standard library structured logging.

command was outputting multi-line JSON which broke the output format.

Remove -track-suppressions flag from gosec SARIF generation. This
prevents #nosec-annotated findings from appearing in GitHub Code
Scanning alerts, as the quality gate was incorrectly flagging them
as new issues.

The PR comment now shows:
- Per-scanner breakdown (Gosec, Bandit, Semgrep, Trivy, etc.)
- Severity counts (high, critical)
- Status icons (✅ ⚠️ ❌) based on severity
- Helpful context for each category

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Each category now has relevant links:
- Secrets: Link to secret scanning alerts
- SAST: Links to Code Scanning filtered by tool (Gosec, Bandit, Semgrep)
- Dependencies: Link to Dependabot alerts
- Licenses: Link to workflow artifacts

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
PR comment now shows:
- Quick summary line with icons at top
- Collapsible <details> section with full breakdown table
- Footer links to workflow run and security overview

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Update github/codeql-action/upload-sarif from v3 to v4 (deprecation)
- Add SARIF validation before upload to prevent 'missing results array' error
- CKB secrets scanner may generate invalid SARIF when no findings

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Track errors from scanner workflows (e.g., invalid SARIF)
- Pass errors to gate workflow
- Display errors prominently in PR comment
- Validates CKB SARIF before upload to prevent silent failures

Restore the emoji styling from the original security-audit.yml:
- 🔐 in title
- ✅/⚠️/❌ status indicators
- Category emojis (🔑, 🛡️, 📦, 📜)
- Per-category pass/warn indicators

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Add detailed collapsible sections matching feature/8.0 style:
- Secret detection details (CKB, Gitleaks, TruffleHog)
- SAST analysis details (Gosec, Semgrep)
- Dependency vulnerabilities (govulncheck, Trivy, OSV)
- License issues (non-permissive licenses)

Each section shows top 5 findings with file:line locations.

- SSE streaming for findReferences and searchSymbols
- Enhanced getStatus with health tiers and remediation
- reindex MCP tool
- Structured error codes with remediation guidance
- Response metadata (ConfidenceFactor, CacheInfo)
