syscall.Exec is not supported on Windows, causing self-update to fail
with "failed to restart: not supported by windows".
Split restart logic into platform-specific files:
- restart_unix.go: Uses syscall.Exec for in-place process replacement
- restart_windows.go: Uses os.Exit(0) to let Windows SCM restart service

covering edge cases like zero deltas, cache handling, NaN/Inf,

The function was using substring matching for sensitive param names,
causing parameters like "extra_token" or "myapikey" to be incorrectly
redacted when they matched "token=" or "apikey=" as substrings.
Now checks for proper boundary characters (? or &) before matching,
so only actual parameter names are redacted.
Related to ADA knowledge entry: "Query param redaction uses substring matching"
Tests cover the hostname lookup paths in HandleLookup:

Add comprehensive test coverage for security-critical URL and token
sanitization functions in config_handlers.go. These functions protect
the setup script endpoint from injection attacks.
TestSanitizeInstallerURL (23 cases): empty/whitespace handling, valid
http/https URLs, fragment stripping, query preservation, control character
rejection, invalid scheme rejection (ftp/file/javascript/data), and
missing host validation.

hex tokens of various lengths (32-128 chars), mixed case hex, control
character rejection, non-hex character rejection, and length validation.
The Telegram bot token redaction had an off-by-one bug: it searched for
the next "/" starting from the "/bot" position, which found the "/" in
"/bot" itself (offset 0) instead of the next "/" after the token.
Result: tokens were not properly redacted and the URL got corrupted with
duplicated path segments, potentially leaking secrets to logs/API responses.
Fix: search from idx+4 (after "/bot") and handle edge cases where there's
no trailing slash (token at end of URL or before query string).
Added 20 comprehensive test cases covering:
- No secrets (passthrough)
- Telegram bot tokens (various patterns)
- Query parameter secrets (token, apikey, api_key, key, secret, password)
- Multiple parameters and edge cases
Extract command status normalization logic from HandleCommandAck into
a dedicated helper function. This improves testability and makes the
status alias handling explicit and documented.
The function accepts client-provided status strings and maps them to
internal status constants:
- acknowledged: "", "ack", "acknowledged"
- completed: "success", "completed", "complete"
- failed: "fail", "failed", "error"
Adds 25 table-driven test cases covering all aliases, case insensitivity,
whitespace handling, and invalid inputs.
Test normalizeLabel, normalizeNodeLabel, splitInstanceKey,
breakerStateToValue, sanitizeInstanceLabels, makeMetricKey,
and makeNodeMetricKey with 36 test cases covering edge cases
like empty strings, whitespace, and invalid inputs.
Move the inline filesystem skip logic from pollVMsAndContainersEfficient
into a reusable ShouldSkipFilesystem function. This consolidates filtering
for virtual filesystems (tmpfs, cgroup, etc.), network mounts (nfs, cifs,
fuse), and special mountpoints (/dev, /proc, /snap, etc.) into one tested
location.
Reduces cyclomatic complexity of pollVMsAndContainersEfficient and adds
28 test cases covering virtual fs types, network mounts, special mounts,
Windows paths, and edge cases.
When api_tokens.json is modified on disk, the ConfigWatcher reloads
the tokens into memory. However, the Monitor's dockerTokenBindings and
hostTokenBindings maps were not synchronized with the new token set,
causing orphaned bindings when agents reconnect after reinstall.
Add SetAPITokenReloadCallback to ConfigWatcher that triggers Monitor's
new RebuildTokenBindings method after token reload. This method
reconstructs the binding maps from current Docker host and host agent
state, keeping only bindings for tokens that still exist in config.
