refactor(repo): uv workspace + hatchling + layout restructure
Migrate from pip-install-e + setuptools to a uv workspace with a
committed uv.lock for deterministic deps. Switch both members to
hatchling, and move package sources into nested standard layout
(l4d2host/l4d2host/, l4d2web/l4d2web/) so builds work from a
read-only source tree — setuptools wrote egg-info to source under
the old layout, which broke uv sync on the root-owned /opt/left4me/src.

Local dev install: `pip install -e ./l4d2host -e ./l4d2web` -> `uv sync`.
.envrc switches from `layout python python3.13` to `use uv`. Python
pinned to 3.13 via .python-version.

l4d2web now declares its cross-dep on l4d2host explicitly via
[tool.uv.sources] (workspace = true). l4d2web/alembic.ini and
l4d2web/alembic/ stay at the project root (standard alembic layout).

Test fixes:
- tests/__init__.py added to both test dirs so pytest doesn't shadow
  l4d2host as a namespace package via outer-dir walk.
- 3 CWD-relative paths in tests (l4d2web/static/css/{tokens,layout}.css
  and js/sse.js) anchored to Path(__file__) so they survive layout
  changes.
- Two test_install.py tests now monkeypatch HOME to tmp_path so they
  stop silently mutating ~/.steam/sdk32 on every run.

628 tests pass under sandboxed `uv run pytest`.

Per docs/superpowers/plans/2026-05-15-uv-workspace-execution.md;
prereq for the ckn-bw bundle's uv-sync action (queued).

# AGENTS.md
Guidance for coding agents working in this repository.
## Mission
Build `left4me` according to the two implementation plans:
- `docs/superpowers/plans/2026-04-22-l4d2-host-lib-v1.md`
- `docs/superpowers/plans/2026-04-23-l4d2-web-app-v1.md`
Do not invent architecture outside these plans unless explicitly requested.
## Current Project State
- `l4d2host/` and `l4d2web/` implementation directories exist.
- Implementation plans remain the source of truth for contract changes and task sequencing.
## Non-Negotiable Constraints
### Workspace and tools
- Do not use git worktrees.
- Repo is a uv workspace; Python is pinned to 3.13 via `.python-version`. After fresh checkout: install `uv` (`brew install uv` / `curl -LsSf https://astral.sh/uv/install.sh | sh`), then `direnv allow` (or `uv sync` directly). See README **Local development** for details.
### Planning artifacts
- Design specs live in `docs/superpowers/specs/` as `YYYY-MM-DD-<topic>-design.md`.
- Implementation plans live in `docs/superpowers/plans/` as `YYYY-MM-DD-<topic>.md` (suffix the topic with `-v1`/`-v2`/etc. if a plan is versioned).
- Commit both to git as soon as the user approves them.
- Do not leave specs or plans outside this repo. The `~/.claude/plans/<slug>.md` plan-mode scratch file is acceptable while plan mode is open; the persisted artifact must end up under `docs/superpowers/` and be committed.
### Naming and boundaries
- Use `l4d2` naming consistently.
- Keep host library and web app as separate components.
- Do not collapse them into one package.
### Host library (`l4d2host` / `l4d2ctl`)
- Exposed CLI write command set is fixed:
- `install`
- `initialize <name> -f <spec.yaml>`
- `start <name>`
- `stop <name>`
- `delete <name>`
- CLI read commands are allowed for web/host boundary consistency:
- `status <name> --json`
- `logs <name> --lines <n> --follow/--no-follow`
- Runtime paths are rooted at `LEFT4ME_ROOT`, defaulting to `/var/lib/left4me`.
- Deployment/config management owns global units under `/usr/local/lib/systemd/system` and privileged helpers under `/usr/local/libexec/left4me`.
- Overlay directories are populated by the web app (workshop downloads, managed-global refresh). The host library only mounts them.
- Fail-fast subprocess behavior; pass raw stderr; propagate return code.
- No lock manager, no rollback, no preflight runtime checks.
- Delete missing instance/runtime dirs must succeed (no-op).
- Read APIs required for web app integration:
- `get_instance_status(name)`
- `stream_instance_logs(name, lines=200, follow=True)`
### Web app (`l4d2-web-app`)
- Flask + server-rendered templates + vendored HTMX.
- No external frontend framework/dependencies.
- Custom CSS with tokenized, consistent link and accent colors.
- Local username/password auth and `admin` flag.
- Persist command logs in `job_logs` table (retain indefinitely).
- Desired vs actual server state model.
- Live logs in UI for both jobs and servers.
- Web app host operations go through `l4d2ctl` via a host command client, not direct `l4d2host` imports.
- Blueprint semantics (locked):
- private per user in v1
- live-linked to servers
- no server-level overrides
- deleting in-use blueprint is blocked
- updates apply on next action
- servers can reassign blueprint anytime
## Delivery Workflow
1. Read both plan files fully before coding.
2. Execute plan tasks in order.
3. Keep changes scoped to one task at a time.
4. Run task-level tests before moving forward.
5. Do not claim completion without command evidence.
6. Keep docs updated when behavior/contracts change.
## Verification Expectations
Before claiming success on any step, run the relevant command and report actual output status.
Typical commands (once components exist):
- `pytest l4d2host/tests -q`
- `pytest l4d2web/tests -q`
## Change Control
- If a requested change conflicts with this file, follow explicit user instruction.
- If plans and code diverge, update plans or flag the mismatch clearly.
