Fix version mismatch: inject version at build time via ldflags

[Copilot]

CLI reports hardcoded 0.3.8 regardless of actual release version.

Changes

• main.go: Replace const VERSION = "0.3.8" with var Version = "dev" settable via -ldflags
• Makefile: Auto-inject version from git tags during build

VERSION ?= $(shell git describe --tags --always --dirty 2>/dev/null || echo "dev")
LDFLAGS=-ldflags "-X main.Version=$(VERSION)"

Now make && ./clickhouse-sql-parser -v outputs v0.4.17 (or current tag).

<issue_title>Version mismatch: Tool reports 0.3.8 while latest release is 0.4.17</issue_title>
<issue_description>Description:

I’ve noticed a discrepancy between the version displayed by the tool and the latest release available on GitHub.

Observed behavior:

When checking the tool’s version via CLI, it reports version 0.3.8.

Expected behavior:

The tool should reflect the latest released version, which is 0.4.17 GitHub releases page.

Environment:

• OS: macOS
• Tool installation method: brew (/opt/homebrew/Cellar/clickhouse-sql-parser/0.4.17: 6 files, 2.8MB)
