* feat: Add dependency cooldown for npm packages
Strip recently-published package versions from npm registry metadata
responses so npm's resolver naturally falls back to older versions.
Overrides the Accept header to force full packument responses (which
include the "time" field needed for publish-date checks).
Reports cooldown blocks only when all versions are stripped (remaining == 0),
matching npm's --min-release-age behavior for silent fallback.
* fix: Report oldest version in cooldown block (shortest wait)
When all versions are blocked by cooldown, report the oldest version
since it exits the cooldown window first — giving the user the
shortest wait time instead of the longest.
* fix: Handle resp.Body.Close error return for errcheck linter
* test: Add dependency cooldown assertions to template config tests
* fix: config template for dependency cooldown
* fix: Prevent npm from caching cooldown-stripped metadata responses
* fix: Restore body on ReadAll failure and log Close errors in response modifier
* fix: Close response body before replacing to prevent connection leak
* fix: Correct daysLeft ceiling math and update ContentLength on error recovery
* fix: Clear Status on status code change and update ContentLength in modifier error path
* refactor: address review comments on dependency cooldown PR
- Make NpmCooldownHandler and constructor package-private
- Pass cooldown days as parameter instead of reading config internally
- Convert standalone functions to methods on npmCooldownHandler
- Set Accept-Encoding: identity to prevent gzip responses breaking JSON parsing
- Return 503 with descriptive message when upstream body read fails
* fix: log errors in stripCooldownVersions instead of swallowing them
* fix: Config preserve fallback defaults
* fix: Code review fixes
* fix: correct cooldown tip to show wait time instead of incorrect trusted_packages advice
* fix: prevent integer overflow in cooldown duration calculation with large days values
* refactor: deduplicate CooldownBlock into internal/models, fix misleading variable names
- Move CooldownBlock struct to internal/models to eliminate duplication
between proxy/interceptors and internal/ui packages
- Simplify proxy_flow.go by using direct assignment instead of field copy
- Rename latestStripped/latestDate to oldestVer/oldestDate for clarity
* fix: Dependency Cooldown Check Encapsulation (#207)
* fix: Encapsulate cooldown check
* feat: Add --skip-dependency-cooldown override
* fix: Code review fixes

When users have HTTP_PROXY/HTTPS_PROXY set in their shell (e.g. corporate
proxy), PMG's upstream transport routes all traffic through that external
proxy — including requests to localhost/127.0.0.1. The external proxy
cannot reach the user's loopback, causing EFAULT/ConnectionRefused errors.
This adds loopback bypass in two places:
- Proxy upstream transport skips external proxy for localhost/127.0.0.1/::1
- Child process env gets NO_PROXY so proxy-aware libs (axios) skip PMG's
proxy for loopback addresses

* docs: Add config merging design spec for #114
Defines the merge-during-setup-install approach for keeping user
configs up to date with new template keys while preserving all
existing values, comments, and formatting.

* docs: Add implementation plan for config merging
TDD-based plan with 6 tasks: dependency setup, failing tests,
core merge implementation, integration test, WriteTemplateConfig
integration, and full verification.

* feat: Merge template config into existing user config during setup install
Instead of skipping when a config file exists, WriteTemplateConfig() now
merges missing keys from the embedded template into the user's config
using YAML AST manipulation. Preserves all user values, comments, and
formatting. Only adds keys present in the template but absent in the
user's config.
Closes#114

* fix: Graceful error handling for config loading and setup commands
Replace panics in loadViperConfig with error returns so the app falls
back to defaults instead of crashing on malformed config files. Add
SilenceUsage to setup install/remove commands so runtime errors don't
dump the full usage text.

The npm postinstall script used `unzip` to extract .zip archives, but
`unzip` is not available by default on Windows, causing installation to
fail with a `spawn UNKNOWN` error. Use PowerShell's `Expand-Archive`
on Windows instead, which is available since PowerShell 5.0 (Windows 10+).
Fixes#187

The spinner goroutine was writing carriage-return + status text to
os.Stdout every 100ms. In the non-interactive TTY path, the child
process also writes directly to os.Stdout, causing both writers to
race on the same file descriptor. The \r emitted by the spinner
resets the cursor to column 0 mid-line, corrupting and truncating
the child process output.
Fix by writing all spinner/status output to os.Stderr, which is the
standard Unix convention for diagnostic and status messages. This is
also consistent with how progress.go and ShowWarning already behave.
