Merge Fin AI best practices into lfx-intercom skill

[clkrueger]

Closes #43

Summary

Merges Fin AI best practices content into the existing lfx-intercom skill rather than maintaining a separate skill, as agreed with @niravpatel27 and @mlehotsky. This makes lfx-intercom the single entry point for all Intercom questions at LFX, with context-based routing to the right section.

What's changed

lfx-intercom/SKILL.md

• Updated description frontmatter to cover both audiences (Angular developers and support/CX teams)
• Added Step 0 — Detect Context routing step: reads the user's request and routes to code integration steps or Fin/CX best practices without asking unless genuinely ambiguous

lfx-intercom/references/fin-best-practices.md (new)

• The 7 pillars of Fin excellence (guidance writing, content strategy, escalation, tagging, etc.)
• Continuous improvement patterns (Topics Explorer, daily review ritual, AI Suggestions)
• Copilot use cases for human agents
• Data quality and conversation tagging patterns
• Real-world benchmarks from production Fin deployments (55% → 80%+ resolution rates)
• Source: Intercom Community expert users and Intercom team members

Acceptance criteria

• Single lfx-intercom skill handles both developer and support/CX Intercom questions
• Routing detects context from user input — only prompts when intent is ambiguous
• Fin best practices content fully intact in references/fin-best-practices.md
• License headers present on all files

Supersedes PR #44.

File	Description

lfx-intercom/SKILL.md:41

• The PR description says Fin best practices are being merged into the existing lfx-intercom skill, but this change also removes the entire previous Angular Intercom integration workflow (Steps 1–7) and leaves the “## Code Integration” section with only a two-line introduction. As-is, the skill no longer provides the canonical integration/audit steps it previously encoded and does not meet the acceptance criterion of handling developer integration questions. Please restore the original integration steps under “## Code Integration”, or move them into a separate reference file and link to it here.

## Code Integration

You are bringing Intercom up to the LFX standard in an Angular application. This
skill handles both fresh installs and fixing/standardizing existing integrations.
