If a single component is specified, the history command will show the full details of the changes made to that component, including commit details if '-O json' is used.

Pull request overview
Adds a new azldev component history subcommand to report per-component change activity (TOML commit counts, customization items, and lock fingerprint-change history), with MCP tool exposure and scenario-level coverage.
Changes:
- Introduces
azldev component historycommand implementation, including JSON output shape and a single-component “card” view. - Adds git helper to count commits touching a specific file efficiently via
git log. - Adds a scenario smoke test and updates the MCP server mode snapshot to include the new tool.

| File | Description |
|---|---|
| scenario/component_history_test.go | New scenario smoke test for component history JSON output and filtering behavior. |
| scenario/snapshots/TestMCPServerMode_1.snap.json | Snapshot updated to include the new MCP tool definition for component-history. |
| internal/utils/git/log.go | New helper for fast per-file commit counting via git log. |
| internal/app/azldev/core/sources/synthistory.go | Adds JSON tags for commit metadata structs used in history output. |
| internal/app/azldev/cmds/component/history.go | New component history command, options, output types, and parallelized metric computation. |
| internal/app/azldev/cmds/component/component.go | Wires the new history subcommand into the component command tree. |
Extract the rendering, customization-collection, and git-metrics logic out of the ~1100-line history.go into history_render.go, history_customizations.go, and history_gitmetrics.go. All files remain in package component; no behavior change.
