huskies: merge 1137 story First-run project init flow — walk through config instead of leaving defaults silently

 - **Phase 4:** git integration — `--git <url>` clones, host SSH key
   mount, push verification.
 - **Phase 5:** per-project resource limits + cleanup chat commands.

 Each phase ships independently and is usable on its own. Phase 1 alone
 gives chat-only users a working project; later phases add the editor

+## First-Run Init Flow (Story 1137)
+
+After a successful `new project ... --adopt` (or any new-project
+bootstrap), the bot appends a **Default configuration** block to the
+adoption success reply.  This block lists every scaffolded agent with
+its model, budget cap, and turn limit, and provides ready-to-send
+override commands.
+
+### Example reply tail
+
+```
+**Default configuration** (3 agents):
+- coder-1 (coder): model=`sonnet`, budget=$5.00, max_turns=50
+- qa (qa): model=`sonnet`, budget=$4.00, max_turns=40
+- mergemaster (mergemaster): model=`sonnet`, budget=$5.00, max_turns=30
+
+Override via chat: `huskies config myapp coder.model=opus`
+Project settings:  `huskies config myapp default_qa=human`
+Accept all defaults silently: add `--skip-config` to the bootstrap command.
+```
+
+### Config override command
+
+```
+huskies config <project> <key>=<value>
+```
+
+The gateway resolves the project's `host_path` from `projects.toml`,
+then writes the setting to `.huskies/agents.toml` or
+`.huskies/project.toml` on the host.
+
+**Agent fields** (`<stage_or_name>.<field>=<value>`):
+
+| Key | Target | Supported values |
+|-----|--------|-----------------|
+| `coder.model` | agents.toml, coder stage | `sonnet`, `opus`, any model string |
+| `qa.model` | agents.toml, qa stage | same |
+| `mergemaster.model` | agents.toml, mergemaster stage | same |
+| `coder.max_turns` | agents.toml, coder stage | integer |
+| `coder.max_budget` | agents.toml, coder stage | decimal (USD) |
+
+**Project keys** (bare `<key>=<value>`):
+
+| Key | Notes |
+|-----|-------|
+| `default_qa` | `"server"`, `"agent"`, or `"human"` |
+| `max_retries` | integer |
+| `max_coders` | integer |
+| `base_branch` | branch name string |
+| `timezone` | IANA timezone (e.g. `"Europe/London"`) |
+| `default_coder_model` | model string |
+
+### Skip path
+
+Pass `--skip-config` to suppress the config block entirely:
+
+```
+new project myapp --adopt /path/to/checkout --skip-config
+```
+
+The success reply is identical to pre-1137 output — only the SSH
+command and registration summary, no agent listing.
