chore: remove graphify (#111)

Removes the graphify integration. It was measured against this repo rather than assumed.

## Why

`graphify query` returns a keyword-seeded BFS neighbourhood, not a location. Asked where CORS origin reflection is implemented, it returned 73 nodes — mostly `api_test.go` helpers, plus a `Reflection and Type Assertions` section from `.agents/skills/golang-performance/references/cpu.md` matched on the word "reflection" — and never named `httpmw/middleware.go:135` or `main.go:121`. `grep` returned both in 39ms. Same shape asking how the poller skips kagane: 145 nodes, top hits `poller_test.go` helpers and two nodes named `T`.

`graphify explain "BrowserFetcher"` is sound (`browser.go L52`, 9 `EXTRACTED` edges), but that is what `lsp references` already answers, against live files instead of a snapshot.

Staleness was never the problem — `graph.json` rebuilt 5s after `f568fb5`, so the git hooks worked. Retrieval quality was.

## What it cost

- Two `PreToolUse` hooks injecting a "MANDATORY: run graphify query first" paragraph into context on **every** grep/find and every source-file read.
- 685k input tokens across 5 build runs (`cost.json`).
- 3.4MB of `graph.json` + `graph.html` tracked, across 11 commits of map-refresh churn.

`AGENTS.md` is the stronger orientation artifact for a repo this size: it carries the CDP constraints, the UTC-clock finding, the per-site adapter list, and the security invariants — none of which an AST graph derives. Graphify earns its keep on repos too large to grep coherently and without curated docs; not this one.

## Changes

- Delete the committed map (`graphify-out/`, -58k lines).
- Drop the `## graphify` rules block from `AGENTS.md` (`CLAUDE.md` is a symlink, so both).
- Drop the five `graphify-out/*` entries from `.gitignore`.
- Empty the two `PreToolUse` hooks in `.claude/settings.json`.
- Remove the stale `graphify query` instruction from `.claude/skills/implement-tickets/SKILL.md` — it pointed dispatched ticket-implementer agents at a binary that no longer exists.

Uninstalled outside the tree (not in this diff): the `graphifyy` CLI, `~/.claude/skills/graphify/`, the global `~/.claude/CLAUDE.md` block, the `Bash(graphify query *)` permission in the git-ignored `.claude/settings.local.json`, and the `post-commit` / `post-checkout` git hooks.

## Verification

`grep -ri graphify` over the worktree is clean; remaining hits are inside `.git/` (commit messages, two stale branch configs). No code touched — backend and userscript are untouched, so `go test ./...` is unaffected.
