… the backup (headroomlabs-ai#1230)

## Description

Makes **tokensave**
([github.com/aovestdipaperino/tokensave](https://github.com/aovestdipaperino/tokensave))
the **primary coding-task compressor** that `headroom wrap` installs,
and demotes **Serena** to a **backup**. tokensave is a local semantic
code-graph MCP server (`tokensave serve`): the agent queries it for
symbols, call chains, and impact analysis instead of grepping/reading
whole files — the same role Serena filled, but as a pre-indexed graph.
Serena now only registers when tokensave is unavailable (or when forced
with `--serena`).

Closes #

## Type of Change

- [ ] Bug fix (non-breaking change that fixes an issue)
- [x] New feature (non-breaking change that adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to change)
- [ ] Documentation update
- [ ] Performance improvement
- [ ] Code refactoring (no functional changes)

## Changes Made

- `headroom/graph/tokensave_installer.py` (new): fetch the prebuilt
tokensave release binary for the platform (release-binary only — no
`cargo` compile at wrap time); honors `HEADROOM_BINARIES_OFFLINE`;
returns `None` (→ Serena) when no asset exists (e.g. x86_64 macOS) or
the download fails.
- `mcp_registry`: `build_tokensave_spec()`; registration/disable/migrate
go through the existing `ServerSpec` + ownership-ledger flow, identical
to Serena.
- `cli/wrap.py`: new `_setup_coding_compressor` primary/backup policy;
tokensave setup/disable/migrate/index helpers. New flags
`--no-tokensave` (skip primary) and `--serena` (force backup on);
`--no-serena` now means "never register the backup". Default wrap
removes a previously Headroom-installed Serena entry once tokensave is
primary (user-managed entries preserved). `--code-graph` repointed to
tokensave; the legacy `codebase-memory-mcp` install path is dropped
(unwrap still cleans up legacy entries). `unwrap claude|codex` remove a
ledger-owned tokensave entry.
- Strands `HeadroomBundle`: `enable_tokensave_mcp=True` (primary);
`enable_serena_mcp` now defaults `False` (backup).
- `docs/content/docs/proxy.mdx`: `--code-graph` description updated from
codebase-memory-mcp to tokensave.
- Tests: tokensave installer (incl. error paths),
register/disable/migrate, primary/backup policy, and the
binary-resolution/indexing helpers. A scoped
`tests/test_cli/conftest.py` offline guard keeps the CLI suite hermetic.

## Testing

- [x] Unit tests pass (`pytest`)
- [x] Linting passes (`ruff check .`)
- [x] Type checking passes (`mypy headroom`)
- [x] New tests added for new functionality
- [ ] Manual testing performed

# Coverage on new module

```

## Real Behavior Proof

- Environment: macOS (darwin arm64), Python 3.14, `uv` dev env;
tokensave 7.0.2 binary present on PATH and exercised against this repo's
`.tokensave/` graph during development. The installer pins release
**v7.0.2** (SHA-256-verified) across macOS arm64, Linux aarch64/x86_64,
and Windows x86_64/aarch64.
- Exact command / steps: `headroom wrap claude` registers `tokensave
serve` as the primary MCP code-graph server and indexes the project;
with the binary removed from PATH and `HEADROOM_BINARIES_OFFLINE=1`, the
same command falls back to registering Serena. Behavior is pinned by the
unit tests (binary-present → tokensave registered + Serena entry
removed; binary-absent → Serena fallback; `--serena` forces backup on;
`--no-serena` suppresses it; `--no-tokensave` disables primary).
- Observed result: tokensave registered as primary on the binary-present
path; Serena registered on the unavailable path; unwrap removes only
ledger-owned entries.
- Not tested: live end-to-end agent session inside Claude Code / Codex
against a real provider API; Windows/Linux release-asset download
(covered by unit tests with mocked archives, not a live fetch).

## Review Readiness

- [x] I have performed a self-review
- [x] This PR is ready for human review

## Checklist

- [x] My code follows the project's style guidelines
- [x] I have performed a self-review of my code
- [x] I have commented my code, particularly in hard-to-understand areas
- [x] I have made corresponding changes to the documentation
- [x] My changes generate no new warnings
- [x] I have added tests that prove my fix is effective or that my
feature works
- [x] New and existing unit tests pass locally with my changes
- [ ] I have updated the CHANGELOG.md if applicable

## Additional Notes

- CHANGELOG is left untouched: this repo generates it via release-please
from Conventional Commits, so a manual edit is N/A.
- `strands/bundle.py` shows 0% patch coverage because that module
hard-imports the optional `strands` SDK, which CI does not install (the
pre-existing `_make_serena_client` was likewise uncovered) — not a
regression.
- A `test (3)` shard failure on `headroom.memory.bridge` is a
pre-existing offline-CI flake (cannot reach huggingface.co); it touches
no file in this PR and the scoped offline guard only applies under
`tests/test_cli/`.
