* feat: add experimental Go module support via pmg go
Adds Go modules as a proxy-guarded ecosystem, opt-in only: the command
runs solely when invoked explicitly as `pmg go ...` and is deliberately
excluded from setup aliases and PATH shims so existing users are
unaffected.
- packagemanager: goPackageManager with fail-safe command classification
(vet/fix excluded from non-download since they can fetch on a cold
cache) and pinned-version extraction where only canonical semver
counts as explicit.
- GOPROXY normalization (fail-closed): effective GOPROXY read via
`go env` (honors go env -w), rebuilt comma-joined with `direct`
dropped so a 403 block is terminal and nothing silently falls back to
unanalyzed VCS fetches. GOPRIVATE/GONOPROXY surface a warning;
GOINSECURE is cleared. Contributed to the proxy flow through a new
ProxyRoutingProvider hook (extra child env + dynamic MITM hosts).
- Go interceptor with dynamic host matching from the user's effective
GOPROXY via InterceptorContext.GoProxyHosts. Malware analysis runs on
.zip only (the sole endpoint that delivers code); .info/.mod/@latest/
list pass through; /sumdb/ traffic and sum.golang.org are never
touched so checksum-db verification stays intact; golang.org/toolchain
is allowed on Go's own checksum verification.
- Dependency cooldown: publish time captured from .info responses
(body unmodified), in-window .zip blocked with 403; fails open for
cooldown only when the publish time was never observed.
- Cert gate: on macOS/Windows `pmg go` fails fast with actionable
guidance unless the persisted PMG CA is OS-trusted (Go ignores
SSL_CERT_FILE there); Linux works via the injected bundle.
- proxye2e: GOPROXY-protocol mock registry, Go driver and 10 hermetic
cases (allow/block/confirm, case-escaped paths, cooldown block and
fail-open, toolchain, sumdb passthrough).
Verified end-to-end on Linux: `pmg go get github.com/google/uuid@v1.6.0`
MITMs proxy.golang.org, analyzes the decoded module at the .zip fetch,
and go.sum verification succeeds through the tunneled checksum db.

* fix(go): address review findings on experimental Go support
- Drop fmt/clean from NonDownloadCommands: both load packages via go
list and can download modules on a cold cache, which would bypass the
proxy under install_only.
- Support GOPROXY entries with a base path (e.g. corp Athens/JFrog at
https://corp/goproxy): the interceptor now receives host -> base URL
and strips the path prefix before parsing module URLs, so verdicts
and cooldown key on the real module path.
- Default unschemed GOPROXY entries to https, matching go's own
behavior, so corp mirrors configured as bare hosts are intercepted
instead of silently unanalyzed.
- Memoize the final verdict per module zip: go re-requests a failed
zip during go get's load phase, which double-recorded stats (the
report showed the same blocked module twice) and would have
re-prompted on Confirm verdicts.
- Fetch .info out-of-band on a cooldown cache miss: go serves .info
from its local module cache on any machine that used go before PMG,
which silently disabled cooldown. Failure of the side-fetch still
fails open for cooldown only.
- Move the noop package resolver into packagemanager.
Verified live: cold-cache cooldown block now records once; warm-cache
rerun is blocked via the side-fetch instead of failing open.

* feat: Show cooldown report for pinned version installs
When a user installs a package with an explicit version (e.g.
npm install foo@1.2.3) and that version falls within the dependency
cooldown window, the cooldown block is now recorded and shown in the
report. Previously, the report only appeared when ALL versions of a
package were in cooldown (remaining == 0), causing pinned version
installs to fail with a confusing "version not found" error from the
package manager instead of a clear cooldown explanation.
Introduces InterceptorContext to carry per-execution data (pinned
versions) from the CLI command through the interceptor layer, keeping
it separate from long-lived dependencies like the analyzer and cache.
* fix: Normalize PyPI pinned version keys for cooldown lookup
CLI-provided package names (e.g. Flask_Cors) don't match the
URL-parsed form (flask-cors). Normalize keys once at construction
time so cooldown lookups match correctly.
* fix: Handle dots in PyPI package name normalization per PEP 503
denormalizePyPIPackageName already documented [-_.] replacement but
only handled underscores. Now also replaces dots with hyphens so
names like zope.interface match the URL-parsed form zope-interface.
* refactor: Extract shared cooldown stats recording into helper
Deduplicate identical stats-recording blocks from npm_cooldown.go
and pypi_cooldown.go into recordCooldownStats in cooldown.go.
* fix: Distinguish explicit version pins from auto-resolved versions
PyPI parsers resolve all packages to concrete versions (even without
a user-specified constraint), so HasVersion() was always true. Add
IsExplicitVersion to PackageInstallTarget, set it only when the user
provided an explicit constraint. Use it in proxy_flow.go to avoid
false pinned-version cooldown reports.
