Pretty-print and color SQL results in terminals

[pratik50]

What changed

• pb sql run now pretty-prints its default output, so query results are easier to read without piping them through jq.
• In a terminal, JSON keys use the active theme color and values stay white. Piped output and -o json remain uncolored, valid JSON for scripts.

Closes #116 (This PR keeps piped SQL output as pretty, uncolored JSON. It improves readability but does not implement the tab-separated output requested in #116.)

Summary by CodeRabbit

• New Features
  • Non-interactive SQL query results now default to pretty-printed JSON arrays, with terminal colors when available. Use -o json for uncolored JSON or -i for the interactive table view.
• Bug Fixes
  • Empty query responses now return an error; empty arrays are displayed as [].
  • Large integers in JSON output retain their original values.

📝 Walkthrough

Walkthrough

SQL responses now use pretty-printed JSON arrays in text and JSON modes. Text output uses terminal coloring when enabled, while JSON output remains uncolored. Empty or whitespace-only response bodies return an error.

Changes

SQL JSON Output

Layer / File(s)	Summary
JSON highlighting styles pkg/ui/highlight.go, pkg/ui/theme.go	HighlightJSON uses a cached style with palette-based token colors. SetActive clears the cached JSON style when it replaces the palette.
SQL response formatting cmd/query.go, cmd/utils.go, cmd/query_test.go, README.md, go.mod	Text and JSON responses share a pretty-printed array formatter. Text output enables terminal coloring when stdout is a terminal, NO_COLOR is unset, TERM is not dumb, and terminal setup succeeds. Empty response bodies return an error. Tests cover formatted arrays, colored output, and preservation of a large integer. The README documents the output modes.

Merge Risk: 🟡 Moderate · up to 984ce

Piped pb sql run text output is multi-line JSON rather than the one-row-per-line format that issue #116 asks for, so line-oriented tools cannot process rows individually. Either implement the row-oriented piped output or confirm that the issue is intentionally not being closed by this change.

Explanation

Issue #116 requires text mode to print one row per line, using a table on a TTY and tab-separated output when piped. In cmd/query.go, the default text path calls streamSQLTextResponse, which delegates to streamSQLResponse and writePrettyJSONArray. This prints a pretty-printed JSON array in both terminal and piped output. The -o json path also prints JSON, so that part of the requirement remains satisfied.
