Three classes of drift cleaned up across 85 .md files:
- Em-dashes: replaced ` — ` with the contextually correct separator
(colon for `term: explanation`, period to split clauses across
sentences/source lines, parentheses for asides, semicolon for
tight-linked continuations). Two intentional exceptions remain
in `docs/contributing/documentation.md` (the rule literal) and
inside a fenced ```sh block in `docs/contributing/actions/debugging/ci.md`.
- SPOT self-labels: rewrote "This is the SPOT for X" to describe
the subject directly ("This directory holds X" / "This file
describes X"). Cross-references to other artefacts' canonical
role remain unchanged.
- Heading-emoji position: moved leading-emoji headings (`# 🧩 Title`)
to trailing position (`# Title 🧩`) per the headline rule that
emojis MUST come after the title text.

Adds scripts/install/sandbox.sh, a distro-aware installer for the OS-level
dependencies the Claude Code sandbox backend needs (bubblewrap, socat),
and exposes it through a new `make agent-install` target. Documents the
target in docs/contributing/tools/make.md, scripts/install/README.md, and
the Claude sandbox guide so contributors on a fresh host can bring up a
working sandbox without hand-installing distro packages.
