[unic-archon-dlc] Full install hook with all config tiers and agent docs

What to build

Expand the install hook from the tracer slice to cover every configuration tier and write the full docs/agents/ set. The hook remains idempotent and additive: re-running it fills in only what is missing.

In scope:

• Skippable tier: e2e test command. If the user defers, the config records e2e_command: null and the hook can fill it in on a later run.
• Defaulted tier (no prompt unless --reconfigure): model profile (balanced), TDD mode (on), Nyquist validation (on), slopsquatting gate (on).
• Label configuration tier (canonical → tracker string mapping):
  • State labels: needs-triage → needs-info → needs-specs → ready-for-agent / ready-for-human → resolved → closed (or rejected). Canonical role names match docs/agents/triage-labels.md from this repo.
  • Type labels: feature, bug, spike, tech-debt, docs.
  • Priority labels: p0, p1, p2, p3.
  • Each canonical name is mapped to the actual string used in the project's tracker.
• Multi-context detection: if CONTEXT-MAP.md exists at repo root, the hook records repo_layout: "multi-context" and discovers per-context CONTEXT.md paths; otherwise "single-context" with the root CONTEXT.md path.
• docs/agents/ outputs (write or update — never clobber unrelated content):
  • issue-tracker.md — already written in slice 1; expand with backend-specific create/update conventions.
  • labels.md — three-tier taxonomy with canonical-to-string mappings for the chosen tracker.
  • branching.md — chosen strategy, default branch names, PR target conventions.
  • domain.md — single-context vs multi-context layout, CONTEXT.md and ADR locations.
  • workflow.md — maps each of the six workflow phases to its artifact outputs and docs/workflow/ paths.
• CLAUDE.md update: append (or update in place) an ## Agent skills block listing each docs/agents/*.md file with a one-line hook. If the block already exists, refresh its contents idempotently.
• Reasonable defaults applied automatically when the tracker is local markdown (canonical strings == tracker strings).

Out of scope: workflow YAML or command file contents (later slices).

Acceptance criteria

• Fresh install writes all five docs/agents/*.md files plus the ## Agent skills block in CLAUDE.md.
• .archon/unic-dlc.config.json includes all label tiers, e2e command (or null), defaulted fields, and repo_layout.
• Multi-context repo (with CONTEXT-MAP.md) is detected and recorded; single-context repo records the root CONTEXT.md path.
• Re-running the hook after the tracer install adds only missing fields; existing fields are preserved unless --reconfigure is passed.
• If CLAUDE.md already has an ## Agent skills block, it is refreshed without duplicating sections or destroying neighbouring content.
• Each docs/agents/*.md matches the canonical-to-tracker mapping in .archon/unic-dlc.config.json (no drift between machine and human readable).
• Tests cover the canonical-to-tracker mapping for at least the local-markdown and GitHub backends.
