feat(manifest): per-file MD directory loader (PRD 0011)
test / unit (pull_request) Successful in 13s
test / integration (pull_request) Successful in 22s

Manifest.resolve walks $HOME/.claude-bottle/{bottles,agents}/ and
$CWD/.claude-bottle/agents/ instead of reading claude-bottle.json.
A bottles/ subdir under $CWD is logged as a warn and ignored —
the filesystem layout IS the trust boundary, no resolver check
needed.

If claude-bottle.json exists alongside no .claude-bottle/ dir at
either location, dies with a clear pointer at the README — the
manifest format changed and we don't silently fall back.

Manifest.from_md_dirs(home, cwd) is the programmatic entry point
tests use to build a Manifest from fixture directories without
touching os.environ. Manifest.from_json_obj is preserved for
tests that still want to build manifests in-memory.

Bottle / agent frontmatter goes through Bottle.from_dict /
Agent.from_dict — same validators as today's JSON path. Unknown
top-level frontmatter keys die with a "did you mean" pointer
listing accepted keys. Filenames that don't match [a-z][a-z0-9-]*
are skipped with a warn.

Agent files accept the Claude Code subagent passthrough fields
(name, description, model, color, memory) so the same file can
drop into ~/.claude/agents/ — claude-bottle ignores them at
launch but doesn't reject.

The dry-run integration test ships a real MD fixture tree now;
all 200 unit + 17 integration tests stay green.

"""Manifest dataclasses. Read claude-bottle.json (cwd + $HOME, deep-merged)
into a frozen, validated Manifest tree.
"""Manifest dataclasses (PRD 0011 layout).
Schema (see CLAUDE.md "Intended design"):
{
"bottles": {
"<bottle-name>": {
"env": { "<NAME>": <env-entry>, ... },
"git": [ <git-entry>, ... ],
"cred_proxy": { "routes": [ <route>, ... ] },
"egress": { "allowlist": [ "<hostname>", ... ] }
}
},
"agents": {
"<agent-name>": {
"skills": [ "<skill-name>", ... ],
"prompt": "<string>",
"bottle": "<bottle-name>"
}
}
}
Reads the per-file manifest tree:
Bottles group shared infrastructure (git upstreams + their gate credentials,
egress allowlist) that multiple agents can reference. Every agent must
reference a bottle.
$HOME/.claude-bottle/bottles/<name>.md — one bottle per file
$HOME/.claude-bottle/agents/<name>.md — home-resident agents
$CWD/.claude-bottle/agents/<name>.md — cwd-supplied agents
Validation runs once at construction (Manifest.from_json_obj) so getters
can trust the shape.
Each file is Markdown with YAML frontmatter. The frontmatter holds
the structured config (see schema below); for agents the body is
the system prompt, for bottles the body is human documentation
(ignored by the parser).
Bottle schema (frontmatter):
env: { <NAME>: <env-entry>, ... }
git: [ <git-entry>, ... ]
cred_proxy: { routes: [ <route>, ... ] }
egress: { allowlist: [ <hostname>, ... ] }
Agent schema (frontmatter):
bottle: <bottle-name> # required
skills: [ <skill-name>, ... ] # optional
# Claude Code subagent passthrough fields — accepted, ignored:
name, description, model, color, memory
The agent file's Markdown body is the system prompt (stripped).
Unknown top-level frontmatter keys die with a hint.
Bottles can ONLY live under $HOME. A bottles/ dir under $CWD is a
warn at load time and contributes nothing. The trust boundary is
expressed as filesystem layout rather than resolver logic.
Validation runs once at load. Manifest.from_json_obj is preserved
as a programmatic entry point (used by tests) that takes a dict
with the same field names — useful for building manifests without
on-disk files.
