feat(learn): common build/test/dev/run/debug commands

 ## [Unreleased]
 
+### Added
+- `qr learn` fills common developer-loop commands into `.qr/profile.json`:
+  `dev_command`, `run_command`, and `debug_command`, plus richer `scripts`
+  defaults for Rust/Go/Python and framework-aware Node fallbacks (Next.js,
+  Vite). Makefile targets and Justfile recipes are merged into `scripts`
+  without clobbering manifest keys. `.qr.toml` can override the new fields.
+
+### Fixed
+- `qr learn` no longer treats plain `main.py` as FastAPI, invents `next lint`,
+  PM-qualifies Makefile/Justfile role commands on Node projects, or records
+  `cargo run` / `go run .` when no runnable binary/root main package exists.
+  Makefile `:=`/`?=` assignments and Justfile `set`/`export`/`alias` lines are
+  skipped; Pipenv projects get a `pipenv run` prefix like uv/poetry/pdm.
 ### Changed
 - Bare `qr go` / `qr g` now opens a lightweight live-filter picker for cached projects while `qr go <project>` keeps the existing direct lookup behavior.

 - `qr do <task>` / `qr d`: natural language → a shell command (run only after explicit confirmation) or a suggested coding-agent hand-off

 - `qr config` / `qr c`: open `config.toml` in your editor (`qr config path` prints its location)
 - `qr doctor`: report the health and location of the config and project cache
 - `qr init` / `qr i`: creates config, installs the shell wrapper, optionally stores your AI key in the OS keychain, prompts to install an hourly rescan cron (default no), and runs an initial scan
