Adding initial tool - dibble the tapir for seeding data (#46122)

## Overview

`dibble` is a one-stop CLI for seeding a Fleet server with test data —
users, teams, policies, reports, labels, scripts, MDM profiles,
software, secrets, CAs, and vulns — replacing ~8 ad-hoc seeding tools
with a single binary.

It makes it easy to:
- **Spin up a populated dev/test server in one command** — `dibble all`
plants everything with sensible, idempotent defaults.
- **Skip the flag-memorization** — running `dibble` with no args
launches an interactive wizard that prompts for Fleet URL, API token,
theme, and which entities to seed, and offers to save the config to
`~/.dibble.yaml`.
- **Seed individual entity types** — `dibble users`, `dibble teams`,
`dibble policies`, etc., when you only need one slice.
- **Get themed, recognizable test data** — pick a theme (hitchhikers,
tng, lotr, ghibli, parksrec, …) so seeded names are easy to eyeball in
the UI.

Hosts are intentionally out of scope — `cmd/osquery-perf` still owns
that. `dibble hosts` is a thin convenience wrapper that picks a fleet,
fetches its enroll secret, and prints/runs the osquery-perf invocation
for you.

## Summary by CodeRabbit

* **New Features**
* Dibble: a CLI tool to seed realistic test data, including an
interactive wizard and subcommands for
teams/users/software/policies/scripts/reports/profiles/labels/activities/enroll-secrets/hosts/vulns,
plus theme-driven “cas” and “ping”.
* Theme system: multiple curated themes to generate consistent seeded
identities, policies, software, labels, and scripts.
* **Chores**
* Ignored the built dibble binary and added a Makefile build target to
compile the dibble tool.

+# Vulnerability performance-test seeder
+
+Bulk MySQL seeder used by the vulnerability performance test harness
+(`tools/software/vulnerabilities/performance_test/tester/`). Writes very large
+numbers of software rows directly to MySQL with deadlock retries.
+
+## Usage
+
+```bash
+go run ./tools/software/vulnerabilities/performance_test/seeder
+```
