#1810 — detection read only .gitignore/.graphifyignore, never
.git/info/exclude, which is where git records local-only excludes and
where `git worktree add` writes nested worktree paths. graphify walked
into those worktree copies and the graph exploded (one 5-worktree repo:
9.4k nodes/10MB -> 210k nodes/311MB, ~77% duplicate). detect now loads
info/exclude at lowest precedence (below every per-dir .gitignore, per
git, so a nearer `!` still wins) and resolves the linked-worktree /
submodule case where `.git` is a file to the shared common git dir.
#1809 — two git-hook gaps: (a) post-checkout never honored
GRAPHIFY_SKIP_HOOK, so the var stopped commit rebuilds but not
branch-switch ones; now checked in both. (b) with core.hooksPath shared
across worktrees, a commit in any linked worktree fired post-commit,
which wrote a rogue delta-only graph.json into it and raced deploy/CI
`git clean` against the detached rebuild. Both hooks now short-circuit
in a linked worktree (git-dir != git-common-dir), comparing ABSOLUTE
paths so the primary checkout (where --git-common-dir is the relative
".git") is never false-positived and skipped.
Adds regression tests: info/exclude honored + negation precedence;
both hooks honor the skip env and carry the worktree guard; and an
end-to-end guard check against a real `git worktree`.
Reported by @cdahl86-cyber (#1810, #1809); the worktree guard was
co-developed with @Claude-Madera's PR #1806.
