feat: add remaining time and group names to grant status (#36)

Track elevation timestamps locally in ~/.grant/cache/session_timestamps.json
so grant status can show remaining session time instead of total duration.
Resolve group names from the groups eligibility API so group sessions display
human-readable names instead of UUIDs.

Both features degrade gracefully: sessions elevated outside grant show total
duration, and unresolved groups fall back to UUID display. JSON output adds
remainingSeconds and groupName as additive omitempty fields.

@@ -9,6 +9,10 @@ All notable changes to this project will be documented in this file.
 - TTY detection with fail-fast: all interactive prompts now return a descriptive error instead of hanging when stdin is not a terminal (pipes, CI, LLM agents)
 - `--output json` / `-o json` global flag for machine-readable output on all commands (`grant`, `env`, `status`, `revoke`, `favorites list`)
 - `grant list` command to discover eligible cloud targets and Entra ID groups without triggering elevation; supports `--provider`, `--groups`, `--refresh`, and `--output json`
+- `grant status` now shows remaining session time instead of total duration for sessions elevated via `grant` or `grant env`; sessions elevated outside the CLI continue to show total duration
+- `grant status` now resolves group names from the groups eligibility API — group sessions display `Group: CloudAdmins in Contoso` instead of `Group: d554b344-uuid in 29cb7961-uuid`
+- JSON output for `grant status` includes new additive fields: `remainingSeconds` (omitted when unknown) and `groupName` (omitted when unresolved)
+- Session elevation timestamps tracked locally in `~/.grant/cache/session_timestamps.json` with automatic cleanup of stale entries

@@ -85,9 +85,11 @@ Custom `SCAAccessService` follows SDK conventions:
 - `--refresh` flag on `grant` and `grant env` bypasses cache reads but still writes fresh data
 - `internal/cache/cache.go` — generic `Store` with `Get[T]`/`Set[T]`, injectable clock for testing
 - `internal/cache/cached_eligibility.go` — `CachedEligibilityLister` decorator implementing `eligibilityLister` + `groupsEligibilityLister`
+- `internal/cache/session_tracker.go` — `RecordSession`, `SessionTimestamps`, `CleanupSessions` for tracking elevation timestamps in `session_timestamps.json` (25h TTL, auto-cleanup of inactive sessions)
 - `buildCachedLister()` in `cmd/root.go` — shared factory used by all commands (root, env, status, revoke, favorites add)
 - Commands without `--refresh` (status, revoke, favorites add) always pass `refresh: false` — they use eligibility for display only
 - Cache failures (read/write) silently fall through to the live API
