The options server's index_revision now also indexes packages when running
under nixpkgs-search, matching the CLI behavior. The packages server gets
its own index_revision tool for standalone package indexing.

Implements a new MCP server that provides read-only access to git
repositories using go-git. Designed for deployment verification by
comparing deployed flake revisions against source repositories.

get_file_at_commit, is_ancestor, commits_between, list_branches,
search_commits.
Includes CLI commands, NixOS module, and comprehensive tests.

Change list_alerts (MCP tool) and alerts (CLI command) to show only
active (non-silenced, non-inhibited) alerts by default. Add state=all
option and --all CLI flag to show all alerts when needed.
- MCP: list_alerts with no state param now returns active alerts only
- MCP: list_alerts with state=all returns all alerts (previous default)
- CLI: alerts command defaults to active, --all shows everything
- Add tests for new default behavior and state=all option
- Update README with new CLI examples
- Bump version to 0.3.0
- Clarify version bumping rules in CLAUDE.md

Add InstructionsFunc callback to ServerConfig, called during each
initialize handshake to generate dynamic instructions. The lab-monitoring
server uses this to query Alertmanager and include a count of active
non-silenced alerts, so the LLM can proactively inform the user.

New MCP server that queries live Prometheus and Alertmanager HTTP APIs
with 8 tools: list_alerts, get_alert, search_metrics, get_metric_metadata,
query (PromQL), list_targets, list_silences, and create_silence.
Extends the MCP core with ModeCustom and NewGenericServer for servers
that don't require a database. Includes CLI with direct commands
(alerts, query, targets, metrics), NixOS module, and comprehensive
httptest-based tests.
Bumps existing binaries to 0.2.1 due to shared internal/mcp change.

Add a new nixpkgs-search CLI that combines NixOS options search with
Nix package search functionality. This provides two MCP servers from
a single binary:
- `nixpkgs-search options serve` for NixOS options
- `nixpkgs-search packages serve` for Nix packages
Key changes:
- Add packages table to database schema (version 3)
- Add Package type and search methods to database layer
- Create internal/packages/ with indexer and parser for nix-env JSON
- Add MCP server mode (options/packages) with separate tool sets
- Add package handlers: search_packages, get_package
- Create cmd/nixpkgs-search with combined indexing support
- Update flake.nix with nixpkgs-search package (now default)
- Bump version to 0.2.0
The index command can index both options and packages together, or
use --no-packages/--no-options flags for partial indexing.

Add support for running the MCP server over HTTP with Server-Sent Events
(SSE) using the MCP Streamable HTTP specification, alongside the existing
STDIO transport.
New features:
- Transport abstraction with Transport interface
- HTTP transport with session management
- SSE support for server-initiated notifications
- CORS security with configurable allowed origins
- Optional TLS support
- CLI flags for HTTP configuration (--transport, --http-address, etc.)
- NixOS module options for HTTP transport
The HTTP transport implements:
- POST /mcp: JSON-RPC requests with session management
- GET /mcp: SSE stream for server notifications
- DELETE /mcp: Session termination
- Origin validation (localhost-only by default)
