The source headers, LICENSE files, and license metadata had drifted
apart. Align the entire project to MIT:
- Convert every source-file header to the MIT text across all comment
styles (Go, TS, TSX, JS, MJS, SQL, CSS, GraphQL, shell), including
SPDX-License-Identifier tags
- Set the root and cookie-banner LICENSE files to the MIT text with a
"MIT License" title line
- Switch the package.json license fields, Docker image label, and
cookie-banner README to MIT
- Update docs and the genmodels header generator accordingly
- Normalize copyright lines to a single format
(Copyright (c) <year(s)> Probo Inc <hello@probo.com>.): unify the
hello@getprobo.com and hello@probo.inc emails to hello@probo.com and
the comma-separated years to a hyphenated range
Genuine third-party references are intentionally left untouched: the
Lucide icon attributions (Lucide is ISC) and the trivy dependency
license allowlist.

Skip empty fingerprints in SystemPromptLeakGuardrail to prevent blank
values from flagging every message. Replace overly broad "sk-" pattern
in SensitiveDataGuardrail with specific LLM provider prefixes
("sk-proj-" for OpenAI, "sk-ant-" for Anthropic) to avoid false
positives on common words like "risk-based" or "task-management".

Introduce a pkg/agent/guardrail package with three guardrails that
can be composed into any agent:
- PromptInjectionGuardrail: LLM-based input classifier that detects
prompt injection attempts before the agent processes them.
- SensitiveDataGuardrail: pattern-based output check for leaked
tokens, keys, connection strings, and raw SQL.
- SystemPromptLeakGuardrail: configurable output check that detects
system prompt content in responses using caller-provided
fingerprints.
The classifier prompt is embedded from a plain text file for easy
review and editing.
