6b73a4b84b feat: Add MCP (Model Context Protocol) server integration
Integrate gin-mcp to expose mining API endpoints as MCP tools,
enabling AI assistants like Claude, Cursor, and Continue to
interact directly with the mining dashboard.

- Add gin-mcp dependency
- Initialize MCP server in SetupRoutes
- Mount at /api/v1/mining/mcp
- Automatically converts 40 API routes to MCP tools

AI assistants can now connect via SSE to discover and call
mining API operations programmatically.

91e7d0f484 perf: Optimize collectMinerStats() for parallel execution
- Collect stats from multiple miners concurrently using goroutines
- Minimize lock duration by taking a snapshot of miners early
- Remove redundant existence check (snapshot is sufficient)
- Extract collectSingleMinerStats for cleaner code
- Add early return when no miners are present

This reduces overall stats collection time when multiple miners
are running, as API calls now happen in parallel instead of
sequentially.

ce5c5034bf fix: Allow removing stopped miners from manager
Previously, StopMiner would fail if the miner was already stopped
(crashed or killed externally), leaving it stuck in the workers list.

Now the miner is always removed from the manager, even if Stop()
returns "miner is not running". This allows cleaning up dead workers.

1351dc7562 fix: Address race conditions and network blocking issues
Critical fixes:
- Release mutex before HTTP calls in GetStats() to prevent blocking
- Fix m.cmd race between Stop() and Wait() goroutine by capturing locally
- Add context support to GetStats() for proper request cancellation

High priority fixes:
- Add existence check in collectMinerStats() before operating on miners
- Add mutex-protected httpClient getter/setter for thread-safe test mocking

Changes:
- Miner interface now requires context.Context for GetStats()
- Stats HTTP requests timeout after 5 seconds (was 30s client default)
- All callers updated to pass context (service uses request context)

9592971678 fix: Address CodeRabbit review findings
- Create api/swagger.md page to properly document Swagger UI access
  instead of linking raw swagger.json in mkdocs nav
- Fix Stop() state management: properly set Running=false and cmd=nil
  on all exit paths, wait for process termination to avoid zombies

68c0033c55 fix: Address high severity security and reliability issues
Security:
- Configure CORS to only allow local origins (localhost, 127.0.0.1, wails://)
- Add CLI args validation for TTMiner to block shell metacharacters
- Add HTTPPort validation (must be 1024-65535)

Reliability:
- Manager.Stop() now stops all running miners before shutdown
- Close stdin pipe on Start() error to prevent resource leak (xmrig, ttminer)
- Fix node_service query parameter parsing (was dead code)

Feature:
- Add TTMiner support in service layer (install, update check, info cache)

006dd3712e fix: Address critical security and concurrency issues
Security fixes:
- Remove hardcoded wallet address from CLI defaults (start.go, serve.go)
  Pool and wallet are now required flags or must be provided explicitly
- Change file permissions from 0644 to 0600 for sensitive config files
  Affects: xmrig config, profiles, settings, config cache
- Fix path traversal in untar() - now returns error instead of silently skipping

Concurrency fix:
- Fix race condition in GetStats() - was using RLock while writing m.FullStats
  Changed to Lock/Unlock in both xmrig_stats.go and ttminer_stats.go

bec2accf1a feat: Add OpenCL GPU support for ProgPowZ, ETChash, and Blake3DCR
Implement GPU mining backends for three new algorithms:

- ProgPowZ (Zano): DAG-based ProgPow variant with 512 parents, dynamic
  program generation per period
- ETChash (Ethereum Classic): Standard Ethash with 256 parents and
  ECIP-1099 epoch calculation for post-block 11.7M
- Blake3DCR (Decred): Simple Blake3 hash kernel with no DAG requirement,
  processing 180-byte block headers

Each implementation includes OpenCL kernels, GPU runners, thread
generators, and build system integration. Also adds fast modulo
optimization to ETCCache for GPU kernel performance.
