459a9c221a Add Codex endpoint support for OpenAI OAuth flow 
Route OpenAI OAuth users through the ChatGPT Codex backend API with
required headers (ChatGPT-Account-Id, originator). The Codex endpoint
requires streaming-only requests, omits unsupported fields (temperature,
max_output_tokens, top_p), and uses a different error format. Also
persists the account ID from OAuth tokens and updates CLI docs for
`fabro ps -q`.

0f565b4a1b Handle OAuth error responses in OpenAI callback server 
When the OAuth provider redirects with an error (e.g. invalid_scope),
the callback server now shows a styled error page and propagates the
error to the CLI instead of failing with a deserialization error.

ea6cdd2cc4 Add -q/--quiet to fabro ps (#64) 
Adds a `-q`/`--quiet` flag to `fabro ps`, mirroring the behavior of
`docker ps -q`. When specified, the command outputs only full run IDs,
one per line, with no headers, footers, or "no runs found"
messages—empty output simply means no matching runs exist.

The quiet flag takes precedence over JSON output, and it composes
naturally with other flags like `-a` (e.g., `fabro ps -qa` lists all run
IDs).

4915fc5378 Add Sentry panic reporting to fabro CLI (#35) 
This PR adds Sentry-based panic reporting to the fabro CLI and improves
the reliability of all background telemetry senders. When the CLI
panics, a Sentry event is serialized to a temp file and uploaded by a
fully detached subprocess, giving visibility into crashes that would
otherwise go unnoticed.

The core infrastructure change is a new `spawn_detached` utility that
uses the double-fork pattern on Unix (fork → setsid → close_fd → fork →
exec) to ensure background subprocesses survive parent exit and terminal
close. This replaces the previous simple `Command::spawn()` approach
used by the analytics sender, which was unreliable since the child could
be killed when the parent exits. Both the analytics sender
(`__send_analytics`) and the new panic sender (`__send_panic`) now share
this `spawn_fabro_subcommand` helper.

The panic module installs a hook early in `main()` that captures panic
info, builds a Sentry event with exception details, stacktrace, and OS
context, then spawns a detached `fabro __send_panic` subprocess to
upload it. It respects the telemetry level setting (no-ops when off),
prevents recursion by setting `FABRO_TELEMETRY=off` in the child,
filters benign "Broken pipe" panics from `| head` usage, and uses a
compile-time `SENTRY_DSN` so dev builds without the DSN set are
unaffected.

139bf5cbef Move sandbox lifecycle into the engine (#22) 
This PR moves sandbox lifecycle management (initialization, setup
commands, devcontainer phases, and cleanup) from the CLI's `run_command`
god function into the workflow engine. Two new engine methods are
introduced: `run_with_lifecycle()` orchestrates sandbox init, fires the
`SandboxReady` hook (now blocking by default), emits a new
`SandboxInitialized` event, handles remote git setup, runs setup
commands and devcontainer lifecycle phases, then delegates to the
existing `run_internal()` graph execution. `cleanup_sandbox()` fires the
`SandboxCleanup` hook and optionally tears down the sandbox. Both
`SandboxReady` and `SandboxCleanup` hook events were previously defined
but never fired — they now fire naturally within the engine alongside
all other hooks.

The CLI is simplified significantly: sandbox record persistence and
progress UI updates are handled via an event listener for
`SandboxInitialized` rather than inline code. The `run_from_branch`
resume path also benefits, gaining hook support and proper cleanup for
free. A new `LifecycleConfig` struct captures setup commands, timeouts,
and devcontainer phases, keeping the engine's API clean. The existing
`run()` method is unchanged, so API server and integration tests
continue working with pre-initialized sandboxes.

The `setup_remote_git` helper is moved from `cli/run.rs` into
`engine.rs` since it only depends on sandbox exec. Config is now passed
by mutable reference to `run_with_lifecycle` so the engine can fill in
remote git fields (base SHA, run branch) that downstream code needs.
Comprehensive tests verify event emission ordering, setup command
execution/failure, and cleanup behavior.

320e2dbe55 Refactor: Collapse pull_request fields on RunConfig into Option<PullRequestConfig> (#21) 
This refactoring collapses four flat `pull_request_*` fields on
`RunConfig` (`pull_request_enabled`, `pull_request_draft`,
`pull_request_auto_merge`, `pull_request_merge_strategy`) into a single
`pull_request: Option<PullRequestConfig>` field. This better represents
the natural tree structure of the configuration: `None` means PR
creation is disabled, while `Some(config)` carries all PR settings
directly.

The PR creation logic in `run.rs` is restructured to use `if let
Some(ref pr_cfg) = config.pull_request` instead of checking a boolean
flag, and construction is simplified to filter out disabled configs at
build time via `.filter(|p| p.enabled).cloned()`. All test constructors
across `engine.rs`, `integration.rs`, `daytona_integration.rs`,
`server.rs`, and `manager_loop.rs` are updated from two lines
(`pull_request_enabled: false, pull_request_draft: false/true`) to a
single `pull_request: None`.

f60e01e16e Fix: Stage durations always show 0s in PR descriptions (#20) 
This PR fixes a bug where stage durations in PR descriptions always
displayed `0s`. The root cause was a key mismatch in
`extract_stage_durations()`: the function was building its HashMap using
`node_label` (human-readable names like `"Preflight Compile"`), but all
three lookup sites were querying by `node_id` (DOT graph identifiers
like `"preflight_compile"`). Every lookup missed and fell back to the
default value of `0`.

The fix changes the HashMap key from `node_label` to `node_id` so that
it matches what the callers actually use for lookups. Additionally, the
existing test is updated so that `node_label` and `node_id` values
differ from each other (e.g., `"plan"` vs `"Plan"`), ensuring the test
would have caught this mismatch before the fix rather than silently
passing due to both fields being identical.

61915dee65 Wire up missing hook invocations (#19) 
This PR wires up three `HookEvent` variants—`StageRetrying`,
`ParallelStart`, and `ParallelComplete`—that were defined in the enum
and documented but never actually invoked by the engine. `StageRetrying`
hooks now fire at both retry sites in `execute_with_retry` (error-retry
and explicit-Retry-status paths) immediately before the backoff sleep.
`ParallelStart` and `ParallelComplete` hooks fire in the parallel
handler after their corresponding event emissions, using a new
`EngineServices::run_hooks()` convenience method since the handler
doesn't have direct access to the engine's hook method.

The two remaining unwired events, `SandboxReady` and `SandboxCleanup`,
are marked as reserved with doc comments on the enum variants and
annotated in the docs table, since wiring them requires sandbox
lifecycle changes outside the engine's scope. A small
`HookContext::set_node()` helper is introduced to reduce repeated field
assignment across all hook call sites, and existing
`StageStart`/`StageComplete` hook calls are refactored to use it.

f7fb72a472 Style SVG output from fabro graph and API (#18) 
This PR styles the SVG output from `fabro graph` and the API graph
endpoints to match the polished look of the documentation SVGs. It
introduces two internal functions in `graph.rs`:
`inject_dot_style_defaults`, which inserts DOT-level defaults
(transparent background, teal `#357f9e` node strokes, gray `#666666`
edges, Helvetica font) after the first `{` in any DOT source, and
`postprocess_svg`, which removes the Graphviz-generated white background
polygon and injects a `<style>` block with `prefers-color-scheme: dark`
media queries for automatic dark mode support.

The `render_dot` function is updated to apply both transformations (DOT
defaults before rendering, SVG post-processing after), and is made `pub`
so the API layer can reuse it. Both `get_graph` in `server.rs` and
`get_run_graph` in `demo/mod.rs` are simplified from ~30 lines of inline
Graphviz process management down to a single call to a shared
`render_dot_svg` helper that delegates to `render_dot` on a blocking
thread.

Six new unit tests validate the styling pipeline: default injection with
and without braces, white background removal, dark mode style insertion,
and the existing SVG integration test is extended to assert styled
output. PNG output is unaffected by the SVG post-processing step.
